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.
