[python-committers] Roundup integration hook added

[Georg Brandl]

Thanks to Kelsey Hightower, we now have a hook that notifies Roundup
of commit messages that reference issues.

*** To make this work, you need to use a hg user name in the form
*** "User Name <email at address>" AND make sure Roundup knows of this
*** email address.  To check this, go to "Your Details" in Roundup
*** and make sure the address is either in "E-mail address" or in
*** "Alternate E-mail addresses".

Then if you put "#12345", "issue 12345" or "issue12345" in a commit
message, this commit message will be added as a comment on the
Roundup issue with a link to the changeset when it is pushed to the
central repo.

If you prefix this with one of "close", "closing", "closed", "closes"
(or the same verb forms of "fix"), the issue will also be closed
automatically.

Please let us know of any bugs you encounter.
