Operator section buttons should not gain focus

[baconbrad]

Two issues arise from having operator buttons gain focus.

A) Setting tab as a hot key will allow a button to gain focus and the operator may become unaware.

B) If a button becomes focused it can be activated with a hot key if it allows it by behavior. (Like spacebar)

Most experienced SBOs will know to avoid this. But I witnessed it tonight in a game which caused a timeout to be accidently fired when the intended action was to start a jam. As a result the jam was automatically dead.
