move bug tracker

[Will Kahn-Greene]

This bug covers moving the bug tracker from bugs.foocorp.net to our
own server.

I asked on the mailing list whether people wanted to switch bug
trackers and there were no strong opinions.

My current problems with redmine are:


1. can't tag bugs -- useful for marking bugs as bitesized (bug
   `#382 </issues/382>`_)
2. mediocre search
3. I'm concerned it won't scale to hundreds of contributors

It's possible I can solve issue 1 if we had our own redmine
instance using a plugin or something. We can push off issue 3. No
one else seems to have problems with issue 2, so we can push that
off, too.

Given that, this bug covers:


1. researching redmine to learn how to set it up and run it
2. figuring out what to do about tags
3. getting a dump of the data from foocorp
4. importing the data into the new bug tracker
5. changing all the urls in the docs and web-site to point to the
   new instance
6. creating some kind of automated something that watches the old
   bug tracker for activity and tells people to use the new one

I'm going to try to get this done for 0.0.4.
