0.11.12

Here is a suggested plan for 0.11.12.

Add Launchpad bug importer

 * fixme

Code cleanups

 * Move Location into a separate table, out of the Person model: http://openhatch.org/bugs/issue175
 * This will let us store geocoded data in the database, dramatically speeding up loading pages within /people/ in many cases
 * We can also then publish the geocoded location data in snapshots, which helps new contributors


 * Remove all uses of celery: http://openhatch.org/bugs/issue292
 * We have very few uses of celery left, and I think we should do this as part of tidying up the code.
