While this is a VERY small update, it is one that has become increasingly required.
Some permissions plugins seem not to update player's displaynames correctly and as such MultiChat was unable to get their display names correctly.
I have now added full support for Vault, meaning that any chat plugin that supports vault will be able to have prefixes, suffixes, etc. fetched by MultiChat to use!
MULTICHAT DOES NOT REQUIRE VAULT!
It is 100% optional and MultiChat will still work perfectly well without it.
