BT: Make native QFontDialog work when using show and changing windows

Cocoa's font manager uses "first responder" which is a great idea, but
breaks as soon as we change windows. Thankfully we can just set the
target and we are OK. An upshot is that we don't need the delegate, but
I'm not going to push my luck on that.
