User List Patch

Description

This patch displays a user list on the logon screen. This is quite useful as people do tend to forget their 4-digit usemod user account ID. However, once they set a UserName, they can recover the UserId? from this user list. This eliminates a lot of duplicate user ID's, and prevents the user database from growing too large. -- UngarPeter
