This is a complete rewrite of cocoa.m to support Core Graphics.

As mentioned in earlier threads, the QuickDraw API is depreciated  
starting with OS X 10.4.
Now with OS X 10.5 it won't even compile QuickDraw code on x86_64.


This implementation of cocoa.m has the following features:

[new] partial drawing of the window as needed, implemented with CG.
[new] fullscreen support
[new] tablet support
[new] View menu and item to enter Fullscreen (cmd-f)
[new] Help menu and items to show qemu-doc.html (cmd-?) and qemu- 
tec.html in the OS X "Help Viewer"
[new] -name is shown in Title-bar of window
[fix] Application menu creation for 10.4+ (API is private as of 10.4)
[fix] Mouse-clicks on the guests window widgets are no longer  
intercepted
[fix] apple keyboard shortcuts forwarded (minimize (cmd-m), hide QEMU  
(cmd-h), quit QEMU (cmd-q))

It should compile on ppc/intel starting form 10.3 (10.2 with the known  
workarounds).

Please test and comment

Mike
