trax: replace clip source

[kevco...@gmail.com]

Hey Guys,

I'm knee deep in trax clips right now, and hitting a wall of problems obviously ;)

Working on some tools to help animators work with clips and clip sources.

I'm not immediately seeing a way to replace a clips source. So that I can keep the clip in trax, with all the blends, and whatnot, and just replace the source.

Help... please ;)

Thanks
Kev
