The Big Image refactor!

Please read:
http://www.blender3d.org/cms/Imaging.834.0.html

Or in short:

- adding MultiLayer Image support
- recoded entire Image API
- better integration of movie/sequence Images

Was a whole load of work... went down for a week to do this. So, will need
a lot of testing! Will be in irc all evening.
