This should make animations in sequencer work again at most
places.
It removes facf0 and facf1 and replaces them by
* effect_fader (the fader position for transition effects
limited 0-1 value range)
* speed_fader (full range fader for speed effect)
Also: default transitions should work again.
Still not working: non-IPO-locked curves. (Don't really know,
if we can / want to bring them back in new animation system.)
To insert keys, use I key while hovering over the button for now, rmb clicking on the property to insert a key doesn't work (general bug for all regions except property editor - will investigate).
Doesn't convert over from old fac0 ipos on opening old files though for the time being.
* Made sequence strip names unique while I was at it, to allow strip properties to be animated properly.
* new operator: set rendersize (SEQUENCE_OT_rendersize) sets the render output size in the current scene to the size of the active sequence strip
* works for movies and images right now
* TODO: currently only works if image or movie strip has been loaded (as in showing the preview for example) - reason is that otherwise the size is not initialized in the strip
Contributors list isnt used much in our C code so probably its easier if people just use svn blame for this.
Can change if this isnt acceptable but I guessed people didnt care so much since most scripts had no header.
