Replace mountpoint selection with combo box.

Instead of entering the mountpoint via a tree browser or manually use a combo
box that lists all available drives / mountpoints. This also allows to easily
add more information like the free and total size for each mountpoint. For
development this can still be overriden by editing the dropdown value manually.
