Commands Table for Help Purposes

The DecBot website is able to query the factoids table to give users a list of factoids. It would be nice to add a table to the DB that can be used to autogenerate a list of other commands. To that end, we could set up a table that drives the main functionality of the bot, such that all commands are configurable, and a help page can be generated automatically.

This would also help with alternative commands. Right now this is all configured in a big ol' dictionary internally.
