[PATCH] stg mail crashes when there is no patch description

stg mail crashes when there is no patch description

The error is:
File "/usr/lib/python2.4/site-packages/stgit/commands/mail.py", line
397, in __build_message
descr = p.get_description().strip()
AttributeError: 'NoneType' object has no attribute 'strip'

This patch tries to handle this a bit better by setting the description
to "<empty message>" and forcing the edit_patches option on.
