Database dependent data may not be kept separate with regard to different database files

[jnharton]

Basically, the code can be told to use a different database, but any other data which is dependent on a database is not necessarily kept separate.

The internal game mail is one such piece of data.

I happened to have two database files, DB1 and DB2 respectively, then user 'admin' on DB1 would have access to the mail of any user 'admin' and vice versa. I.e. no matter how many databases I use there is only one mail file for user 'admin'. The first one will be a new mail file and thereafter all other admins will get that, barring creating a new character with that name.

Consequently, that file might get overwritten if another DB is used and a new character is created with the same name as an existing character in another one.

Obviously this is something that ought to be dealt with, because it's really dumb.
