IRC update: removing MODE and NAMES capabilities

Please don’t remove NAMES (until /chatters is officially documented and supported)

It’s critical for my bot to accurately measure viewer engagement and reward loyalty points. My entire channel concept is built around viewers accruing loyalty currency to spend on voting for the next game I will play. I have a small community, and most of my viewers are loyal enough to stay in chat all the time. With this change, my bot won’t be able to know they have been there the entire time, so it will punish my most loyal lurking viewers. If some more-accurate replacement for NAMES can be rolled out, that would be acceptable, but please don’t remove it while there is no workaround for bots in place!
