This adds MULTICAM-editing support for blender. (Well, the beginning of.)

There is now a new effect track, named MULTICAM, which just selects
one of the lower tracks.

Doesn't sound that exciting, but if you combine this with A/B-Trim (moving
split points of two directly connected tracks around, while magically
resizing both strips, something to be added), you just do:

* add several tracks for your camera angles
* (optionally) sync those tracks
* add one multicam track on top

Use that multicam-track to edit your movie. (Either using fcurves on the
multicam source selector or using knife-tool and A/B-Trim.)

Compare that to:

* add several tracks
* add cross fades between them
* do some python scripting to add several fcurves to make that beast
  somewhat work.
* cry out loud, using it, if you have to move cut points around

Alternatively, even harder:

* just edit the old way and put strip after strip

You might think, that this isn't really helpfull for animators, but
consider using scene-strips (in OpenGL-mode) for input, that are set for
different camera angles and can now be intercut a lot more easily...

Also: small fix on the way: the speed effect can now be used in cascade.
(Don't know, if anyone used it that way, but now it works.)
