Enable Qt3Support for Qt/Cocoa on Mac OS X.

Qt on Mac OS X should not be the only desktop platform
without Qt3Support once the Carpon port is dropped. This
will also make the switch from Carbon to Cocoa-based Qt
as smooth as possible.

This is a minimal port, with some code removed:
Q3FileDialog is gone.
Q3MainWindow won't get the "hide toolbar" button.
Q3ScrollView might to more updates than structly neccesary.

The rest is there, including the QT3_SUPPORT functions
in QtCore and QtGui.
