Mee: Filter out following text (#2835)

Before, `/mee` didn't used to allow for a target that started with a number or letter, as this could lead to impersonation.

Ex: `/mee 2 tests` - if you're name is bobbyuser, then it would appear as "bobbyuser2 tests" in the chat.

This makes it so the the target of `/mee` cannot start with a number or letter.
