Major code restructure to allow Cocoa to work correctly. Cocoa requires that the application loop run on the very first OS thread created, not just an any ordinary thread. To support this, your code must now be run by the UI init code. Windows and Unix builds still work fine; Mac OS X fails for reasons I now have to debug.
