The wipe tower now respects filament max volumetric flow

Browse Source 
The odd commands that lowered the speed override values for PVA, FLEX etc. were removed

Now the wipe tower backups user speed override, sets it to 100%, does what is needed
and restores the old value when finished. There are no special cases - lowering
the speed for certain materials can be achieved by lowering the volumetric flow.
