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.

#!/bin/sh

hg init a
echo a > a/a
hg --cwd a ci -Ama

hg clone a c

hg clone a b
echo b >> b/a
hg --cwd b ci -mb

echo % push should push to default when default-push not set
hg --cwd b push | sed 's/pushing to.*/pushing/'

echo % push should push to default-push when set
echo 'default-push = ../c' >> b/.hg/hgrc
hg --cwd b push | sed 's/pushing to.*/pushing/'
