Title: Removed forced brackets from chat prefix.

I dont think MV should force brackets around the world prefix. Leave that up to the user to mess with in the alias section.

Essentials chat in game looks like this for me [worldname] Tunix2: blah blah
and I would much rather do something like worldname: Tunix2: blah blah

If It were up to me id add this to the config file:
chatprefixformat: '{world}'

so users can chatprefixformat: 'World:{world}' or chatprefixformat: 'w:{world}'
