account rename

[Mark Sir Link]

I, and I would guess others with spaces in their account names would appreciate a free account rename.

For text based commands used in events and other activities on servers, using them on me becomes a chore, especially for those who are unaware of how to do so (adding quotes).

It has also made things difficult on things like the Testbed server, since it seems near impossible to correctly give read/write rights to directories with spaces in the names.
