Indicate keyboard focus

[peterbjornx]

Using any of the spinner or text input fields steals focus from the main program, making keybindings no longer work. This is confusing and requiress the user to click the main viewport, which if not carefully done can result in editing actions.

A good solution would be to add a clear indicator that the keyboard is active, such as a border around the viewport, and possibly to return to idle mode when losing focus.
