Add QMacPasteboardMime.

Equivalent to QMacPasteboardMime from Qt 4. Requires
exported functions from QPlatformNativeInterface.

The API from Qt 4 is in large parts kept, with the
exception of the static functions used internally
by Qt (?)

The implementation is based on having two equal classes
and keeping them in sync: One internal to the Cocoa 
platform plugin and one public in QtMacExtras.
