23f54076db BGE: Added getActionName() function to KX_GameObject()
It works similar to getActionFrame(), you have to give a layer or not (for layer 0) as the argument and it returns the name of the animation that the object is currently playing.

Example:

```
import bge
own = bge.logic.getCurrentController().owner
own.playAction("SomeAction",0,20)
print(own.getActionName())
```
>> SomeAction

Here is an example file, just open the blend file with the terminal opened
and press P, you can see how the current animation is being printed:
{F217484}

9f48aa45ad BGE: added clamping of angular velocity.
Angular velocity clamping was missing from the BGE. It is implemented
similarly to the linear velocity clamping. It is needed to be able to
drive physical simulations of systems that have a limited rotational

62f79856e9 BGE : Standardization of callbacks execution.
A new function (RunPythonCallBackList) to call all python functions
contained in a python list was developed.

This function has:
  - first argument is the python list of callbacks
  - second argument is a python list of arguments
  - third argument is the minimum quantity of arguments
  - forth argument is the maximum quantity of arguments

It improves flexibility and supports *args.

3d55859924 BGE: Support for collision group/mask from the api + activated on EndObject.
A Python API for the collision group / mask has been added:
```
KX_GameObject.collisionGroup
KX_GameObject.collisionMask
```
The maximum number of collision groups and masked has been increased from eight to sixteen.
This means that the max value of collisionGroup/Mask is (2 ** 16) - 1

EndObject will now activate objects that were sleeping and colliding with the removed object.
This means that, unlike now, if a rigid body starts sleeping on top of another object, when the latter is removed the rigid body will activate and fall, rather than float midair as before.

Collision groups that do not intersect used to collide on the first frame. Now this has been fixed so that they collide appropriately.

Thanks to agoose77 for his help.

e7d051043d BGE: New hysteresis offset to improve LOD level transitions
This change introduces a new hysteresis parameter that it will be added
or subtracted to/from the LOD distance to avoid popping when a LOD
object moves close to the LOD transition continuously.

Then, we have the following:

- a new LOD Hysteresis setting per scene (default 10%) which is located
in Scene context --> Level of Detail panel. This scene parameter also
will active/deactive the scene hysteresis.
- and a new LOD Hysteresis setting per object (default 10%) which is
located in Object context --> Levels of Detail panel. The LOD hysteresis
setting per object (if active) will overwrite the hysteresis setting per
scene value.

For the new blends: the hysteresis setting per scene would be active by
default and the per object would be inactive by default.
For the old blends: both hysteresis settings (per scene and per object)
would be inactive by default. A quick way to take advantage of this
feature for old blends would be to activate the hysteresis parameter in
the scene context -> Level of Detail panel

225027ce5d BGE - new read-only attribute in KX_GameObject python api (LOD level)
Added a new "current_lod_level" property to the python api of
KX_GameObject. The property returns the current lod level of the game
object. The purpose of the property is activate logic routines only when
an object is at a certain lod-distance from the camera, avoiding to
separately recomputing the same distance in the logic script. Usage in
python script might look like:

owner = bge.logic.getCurrentController().owner
lod_level = owner.currentLodLevel
if lod_level == 0: ...do something
else: ... object might be too distant

dd65a44c9a BGE physics: When colliding, report first contact point to Python
This patch adds two parameters to the functions in the
collisionCallbacks list. The callback function should thus be like
this:

```
def on_colliding(other, point, normal):
    print("Colliding with %s at %s with normal %s" % (other, point, normal))

game_ob.collisionCallbacks.append(on_colliding)
```

The `point` parameter will contain the collision point in world
coordinates on the current object, and the `normal` contains the
surface normal at the collision point.

The callback functions are checked for the number of arguments
`co_argcount`. The new `point` and `normal` arguments are only passed
when `co_argcount > 1` or when `co_argcount` cannot be determined.

ed8dc78691 BGE physics: get/set linear and angular damping
This patch adds the following R/W properties and method to `KX_GameObject`:

  - `linearDamping`  -- get/set linear damping
  - `angluarDamping`  -- get/set angular damping
  - `setDamping(linear, angular)` -- set both simultaneously

These allow runtime changes to the same properties that are accessible at design time in Blender's UI via `game.damping` and `game.rotation_damping`. The names of the properties were chosen to mirror the internal names of the BGE physics engine, as these are (AFAIK) also the commonly used names in physics literature.

1f43b083a9 BGE: Fix for applyImpulse function
This is related to task T29419. Credit also goes to Goran Milovanovic
(goran) for proposing an initial fix for this issue.

The issue is the current behavior of applyImpulse doesn't match the behavior
described in the documentation as instead of a impulse point in world coordinates,
it seems to require a coordinate in a local space.

Additionally, applyImpulse function isn't consistent with similar functions (applyForce, applyTorque, etc)
as it doesn't allow  to choose in which space (local or global) the impulse is applied.

Now, we have the following function:

applyImpulse(point, impulse, local=False)
being "point" the point to apply the impulse to (in world or local coordinates). When local is False will
have both point and impulse in World space and when local is True will have point and impulse in local space.

60c8c130fe BGE cleanup: KX_GameObject::GetParent() no longer increases the object's refcount.
I'm not sure why this function ever increased the object's refcount. Any
place in the code that calls KX_GameObject::GetParent() has to turn
around and call parent->Release(). Forgetting to call Release() was a
common cause of memory leaks (in fact, KX_SteeringActuator was probably
leaking). If the refcount needs to be increased, the calling code can
handle calling AddRef().
