* Lots of cleanup and refactoring
* Removed LFG and LFR output (it's just spam and honestly nobody in a random group cares about your achievements, and they'll probably see them anyway since they're nearby)
* Removed Say output (everyone around you can see you getting the achievement anyway)
* Custom channel output now refuses to output to General, Trade, and LocalDefense (spam, and nobody cares about your achievements)

Still needs testing in LFG and LFR situations, both queued up alone and with friends
