Add setting to hide the status completely

[djoffe]

The cursor appearance change is enough indication, so an option to hide the status altogether (instead of just abbreviating) might save space in the status bar.

ps: Thanks for the extension. It is most useful!

Hey, that is a spectacular idea! I'll work on that for the next release.
