Create a unified location microformat partial.

All 3 are real similar but with slight differences. The g5-foundation
gem that can take a location UID and return a virtus model uses the
location's show page, while Bauer's engine (which I am refactoring to
use that same parsing logic) uses the client's show page. I don't want
any inconsistencies in the two versions ofthat markup to screw things
up.

I tried to spotcheck the fields in these as I removed them in favor of
the partial, but let's be realistic here... it's possible I missed
something.
