Adding the db_orm class and tests.
Getting db_orm integrated.  Most of the routes now use db_orm.
Requests are now using db_orm.

Leaving db around for now.  There are still places in testing where it's easier to use.
Clean up some more places where lib/db was being used.  There are still lots
of places where it is being used and some of them can't easily be eliminated,
especially where raw queries are being used.
