Quicktime for Cocoa : import part
This makes quicktime import (.mov & quicktime handled image files such as .gif) available also for 64bit OSX

Unfortunately, Apple currently incomplete implementation of QTKit has much lower performance than old Carbon Quicktime.
FYI, it spawns a 32bit process "QTKitserver" to place calls to Quicktime 7.

So this is mostly meant as a "backup" for 64bit OSX builds, until Apple releases full Quicktime X.

Export part will come just after.

CMake scripts updated: set WITH_QUICKTIME and USE_QTKIT to ON
