mq/qqueue: add --purge option to delete a queue and its patch dir

qqueue --delete only deletes the reference to the queue, and leaves
the associated patch directory behind. There is no Mercurial-way of
getting rid of that patch directory afterward.

This patch adds the --purge option to qqueue, that deletes the queue
from the list, and also removes the associated patch dir. If the queue
was non-existant, but the patch dir was, it is removed nonetheless.

This is to avoid manual intervention in the .hg directory.

    hg ci -m "a -> $i"

    hg cp $i other-file
    echo "different" >> $i
    hg ci -m "$i -> other-file"
