Adds console renderer to merger backend.

Adds console renderer to merger backend.

This CL:
a) creates a backend url that serves a merged console table (sans surroundings,
javascript, announce header, and css).
b) does some minor cleanup of the other backend code;
c) changes tests to reflect slightly modified data storage formats; and
d) still doesn't affect the current front-end.

The next (and final, in this project) CL will:
a) add pre-rendering and caching; and
b) change the frontend to use this new renderer.

The main body of the change is in merger.py. Some minor parsing changes were
made in app.py to make the backend and datastore storage model a bit more
consistent and sane. Corresponding changes were made to the tests.

Due to the data formatting changes, this will require a datastore and memcache
purge when it goes live, but that's not a problem. I'll just do it at a
low-traffic time and nurse it a bit.
