check if all rights needed for mysql are correctly set..that means create tables, alter tables and so on..

Example: alter table is not allowed to the user->there is no mysql failure message either in install tool nor in extension manager when installing a new extension, which wants to alter tables.
So the user didn't know why his extensions wouldn't work.

Perhaps it's not necessary to check the rights, but the results of the sql statements should be checked anyway!
