Cocoa: ignore mouseDown events in a window's titlebar.

These events accidentally slipping in sometimes appears to be a bug (or maybe new behavior) in 10.10, as previous versions of Mac OS X don't appear to ever trigger this. Thanks to Paulo Marques for pointing out the fix on the SDL mailing list! Fixes Bugzilla #2842 (again).
