PREP: Added new config vars for opme trap to be implemented...
removed an extra file... e.e
added more vars to config... added migration for old vars to new ones
moved shownick to branch from notify (it's only in notifications)
added shownick.enabled since shownick is a marker
modified code to use new config tags
bump to 2.3 for code release later on... 2.2 is internal only
updated config.yml to reflect new layout
