plugin.yml update

Removed unused permissions.
Added a few permissions not in use, anymore.
config.yml update

config.yml now contains semi-comprehensive notes. Shouldn't make
browsing the file too difficult, but now everything should be
understandable.
PlayerManager update

Instead of setting the result in switch, a boolean is now set, and
called against later. This should decrease overall command line usage
later on, when more methods for focus are available.

Now implement notifications on deny.
