Feature request: Make the name Mjolnir responds to configurable.

[virtadpt]

How tricky would it be to make the name the Mjolnir bot responds to configurable? Calling it with !mjolnir works, to be fair, but when the account's not named mjolnir:matrix.example.com it can be a bit confusing, especially when the banhammer must be swung in broad arcs, if you catch my drift.

Being able to set an arbitrary name in the config file (like !anton or !nuke) but defaulting to !mjolnir would be really handy.

@virtadpt From what I can see, it should be as simple as making COMMAND_PREFIX modifiable via the config file, and optionally also use the given prefix in the help/status messages, instead of hard-coding the prefix into the message.

What's wrong with just using the bot's display name? You can already tab complete and ping the bot instead of using !mjolnir.
