Make AttackBot use Regex for name parsing

[Strik3ria]

Some OTs make modifications to monster names and so it may be useful for servers like Blazera.net who add monster levels and things up that nature to names so we can still target specific monsters with the bot. For example to make it work for blazera I have to change the attackbot name parsing so that it strips out [MB] from the beginning if it is there and [L.123] from the end of the name. If I could just put .creature-name. it would make things much easier I think.
