Added AvfWriter stub file
Added some basic components to MovieWriter
Added a note.
commented out lots of code that's just not going to work. Refactoring using Surface objects only (no CVPixelBuffers)
Fixed errors. Updated MovieWriter::addFrame method.

Doesn't work yet, but it's one step closer.
Added bits of code to implementations however, nothing is really working still.
Added AVF capture classes. Removed unwanted legacy files.

The new classes are migrated from Cinder. They'll just be refactored to support the desktop.
