Add permissions command

Sets, lists, and removes user permissions.
First command to use the new regex trigger system
Add permissions bot

This is sooo not done yet and it bugs me to push it
Add getPermission(String, boolean)

Allows the PermissionsFactory to return a null Permission.
Allows the bot to check whether a permission exists
Fix bug where readPermissions returned an empty Permission name

Haha, oops
Introduce logging system

Major bugs. Seriously unfinished code here, will work more tomorrow
Add logging system example bot

Known issue: PircBot#setVerbose(boolean) does NOTHING as used in the
constructor here. Figure out why.
