[Encyclopedia] Add configuration option to decide whether to respond with factoids by Botname: prefixed messages

[Thomas Ward]

This is a feature request.

Currently, when using Supybot with Encyclopedia, if you do "Botname: something", if something is a command for the bot but not a factoid the system still processes it as if its a factoid, as well as processing it as a command. I'd like to see a configurable option to enable/disable botname-prefixed responders within the Encyclopedia plugin, similar to how Supybot core has such an option for command processing.
