Switch Mac plugins back to a UI runloop

This makes Cocoa-event plugins (e.g., Flash 10.1 preview) happier, and Carbon full-screen still gets key events.

BUG=28000
TEST=Flash 10.1 preview should play even without mouse movement. Flash 10 full screen should still accept keyboard commands (e.g., esc).
