Request Removal banned accounts in RuneMate

For people with quite a lot of accounts that they also manage inside the RuneMate client, it's quite the ordeal to remove banned accounts when there's over 20 accounts in the list. You'd have to test every account individually.

RuneMate already recognizes if an account gets banned, you get the red-colored client alert. It wouldn't be too hard I assume to remove the account you selected to start the bot with to be removed from the account list. That way we keep the list tidy, which saves a lot of users a lot of effort.

Ideally there'd be a switch to toggle this on and off, so people can make the choice themselves.
