Emulator

See attached screenshots for a comparison between how Wx and Qt sized this button.

This is a very small nitpick, but something that's annoyed me since switching to Qt. The "Generate a New Statistics Identity" button is unnecessarily wide, and were it changed to be only as wide as the text on the button, I think it would look much better.

I would recommend putting it on the same line as the "enable usage statistics reporting" checkbox.
