[Cin] Library updates to CinGG

[Andrea paz]

I tried various loading tests and render with tiff. All OK. I also
tried a background render, again with tiff, and that also works fine.
I tried a render from mp3 to flac and that is also without problems.
Renders of tiff sequences and flac can be reloaded in CinGG without
problems. As far as libjpeg-turbo is concerned, I've only tried normal
jpgs without any problems, so I don't know if it's helpful...
Thanks!
