Custom Message Prefixs

[Alkali-Metal]

Currently the only way to change the message prefix is by going into the code and changing it in the message parser, but what I was thinking is maybe something in the !config command (Of course the prefix would be whatever you have it at at that point it time) and this would be a nice feature as it would be nice if some people are used to other prefix's coming over from other bot's then they can adjust the prefix so that it is a gradual transition over.

[Alkali] !config prefix ~
[CactusBot] Prefix updated to "~"
[Alkali] !cactus
<No response>
[Alkali] ~cactus
[CactusBot] Ohai, I'm CactusBot! :cactus
