Fixed MHWD config dependencies not working. Details: y/n prompt would always exit the function and never commit the transaction. Fixing the check would've worked, but this breaks the QT gui.
Mark all installed packages as explicitly installed (this has to be done with a separate command!), mark OPTREM packages as --asdeps instead of removing them. This makes it the users' responsibility to remove orphans, which is the best compromise in my opinion.
