QTKit (OSX 64bit): Add audio export to Quicktime

Supports default OSX codecs : Linear PCM, Apple Lossless and AAC

Note that AAC codec doesn't support sample rates above 48kHz. If a python/rna guru knows how to easily enforce this limit, he is welcome!

Enjoy making Quicktime movies now with audio!
