SCons updates: (All done by jesterKing)

* Windows .exe file now includes the blender icon.
* Builds with game engine on Windows only.
  I tried building the game engine on Linux, but I get weird errors when
  building with ode. There's a dirty #include path in
  Physics/BlOde/OdePhysicsEnvironment.cpp (../ode/src/joint.h). gcc doesn't
  like this somehow.
* Other platforms need to add a couple of flags to the SConstruct:
  use_sumo, use_ode, solid_include and ode_include
