Add mass updater to run migrations of rethink tables

add two migrations
start work on interface/glue script to allow working with, choosing and
selectively running migrations
chmod +x a few things
finish migrate.py

add initial tests by removing all replace(" ", "_")'s in phots. Should work
just fine still hopefully.
