[PATCH] notmuch new: add a --in-directory option

[Mark Walters <markwalters1009@gmail.com>]

This patch adds a --in-directory=folder option to notmuch new which
tells it to only check for new messages inside folder (relative to the
database root)
---

NOTE This is only very lightly tested (but seems to work) so please
make sure you backup the notmuch database before testing!
