Add FocusProtection features

The apps file gets a new key
FocusProtection
supporting a comma separated list.
* None : regular behavior
* Lock : If this window has the focus, no other may claim it
* Deny : This window is not allowed to focus itself

I addition there's preparation for a follow-up patch to incorporate and
substitute the present FocusNewWindow feature:
* Gain : Pass focus to new window
* Refuse : Do not pass focus to new window

rationale:
clients stealing the focus sucks badly and while there's an input driven
timeout, that only protects actual typing flow, but if eg. vlc proceeds on
the playlist, you'll suddenly control vlc instead of your browser
(ie. typing ctrl+w doesn't close the tab, but the playlist ...)
