Well... I didn't want to commit this before creating single-button
forms for enabling/disabling modules. However part of this accidentally
made it through, so let's finish it.
Still some work to do, but it already looks far better like this.
refs #4095
BaseQuery should no longer be abstract but be usable as is as soon as
we stripped ResultSet-specific tasks. As "Base" suggests something that
must be extended, the name no longer fits. So this is SimpleQuery right
now.
the Monitoring/View code was completly dropped in favor of
the DataView implementations, as new Backends otherwise
would require to implement two seperate query logics
