Add "wait" command to array of blocked words

TPP added a new command recently, the "**wait**" command which only appears in democracy mode. We aren't currently filtering this in the chat so there a whole bunch of "waits" popping up right now in the talk section of the chat and making it hard to read things. I went ahead and added it to the array of blocked words as a quick fix. I tested it out and it works great.

If you want me to include a new minified version as part of this branch as well let me know and I'll do that.
