Do not change the current Directory

Qt has a really strange API for directories. when you create a QDir
and set's the currentDir on *that* QDir you created, it's for the
whole application and not just for that variable. Then when the
variable is out of scope, the directory doesn't change back - ugh.

The solution is not to call setCurrentDir on the newly created QDir (which
was quite good since it's also a code cleanup. )

[Dirk Hohndel: modified to undo the far less elegant fix I had made in an
               earlier commit]
