Allow new bots to be added without requiring a server restart

Made read bot names from a file, or maybe the require 'bots.rb' could simply be replaced with include 'bots.rb' (where include may not be the right function name, it might be import or something of the like, I can't remember now. The important point is that the file needs to be reread every time the script is executed).

Does not work on the front-end in production due to require_reloader being limited to development but I'm not sure why. Have to dig into require_reloader more.

Should have bots in a plain data config file. JSON might make the file easier to use on the client side, but YAML might allow the use of Ruby variables, like the constants in acpc_dealer, which would be useful.
