Implement a completely new user manager (look + feel + logic):
- Accounts and existing privileges are presented in a pulldown which makes it as
easy to use as a toy
- Adding privileges calls the new SelectDBO dialog which is basically a tree
like childwins dbtree
- Updating accounts canonicalizes various odd/legacy mechanisms in the MySQL
user system
- Fullfills feature request #1547437 (btw)
- Wants to be tested heavily on different servers

A result of a team work. 1000 thanks to rosenfield for the admin friendly logic
implementation, tons of fixes and usability ideas.
