first part of SQL-support

* more refactorization
* partial implementation of SQLUser
* partial implementation of SQLPermissions
changed internal interface IDataProvider
more work on SQL-support (still incomplete)
implement getInfo() for SQL-support
remove timed commands

was a hack that never got used and makes SQL stuff more complicated.
timed permissions will be easier to implement via MySQL
removed leftover pieces of timed-commands
more work on SQL-support (nearly finished)
complete SQL-support (probably still buggy)
Merge branch 'feature/sqlsupport' into develop
