add more option to the AI plugin

[Uncommon-34]

eg: limit the bot to only respond in one channel and/or black list channels (maybe have a white list a black list for channels and also have a free talk option to replace current whitelist??? ), also maybe add a white list and blacklist for roles so people with certain roles can talk to the bot. I'm doing this at the minute with middleware but my god was that a pain just a option would make it easier for everyone in the future. also updated readme.md in the AI area as it docent explain everything like it referencing materials in docs folder well and show all options there are there.
