"Safer" user char deletion and better account char handling

[GoogleCodeExporter]

The characters in an account should be in a separate lookup table 
(account_character), not inline on Character.

When deleting the characters from an account, mark the character as "deleted" 
(preferably with a timestamp on when it was deleted) in the account_character 
table. And don't actually delete the character. It is very useful to avoid 
actually deleting a user's characters for numerous reasons, even if it is not 
linked to an account.
