multiview: cleanup (removing uneeded variables and changes)
multiview: temp commit, OSA still not working, and Cycles not working in
some times
multiview: README update - listing where I'm stuck at now :/
multiview: shouldn't write MultiView header when only rendering one view
multiview: first take on supporting MultiPart (OpenEXR 2.0)
Things are still not working, but I'm working on that.
The big problem now is that I have passes with more than 4 channels,
which Blender seems not to like very much.

An alternative is to force each view to be its own pass, though
it's not so elegant. Another option is to bring view to a higher
level as it was once considered.
multiview: load/save multipart exr + wip code

current problems:
-----------------
1) loading multipart exrs is producing a one line glitch in the first
   view (on the left). I have no idea way.

2) FSA merging is not working (the whole 'Combined' thing).
   I'm lead to believe this is the same problem of Coposite.

3) when using "Save Buffers" (or FSA) the buffers are upside-down
   It's not the end of the world ... details hehe
multiview: save multipart finally up and running
multiview: SaveBuffers fix : we need to force the version of tmp file to 2.43

I'll fix that next, but for now it does work.
multiview: fix for "offset" in multipart images
multiview: fix for anti-alias render
