Change the database layout so that the breakdown table now references
tests relationally in a new awfy_suite_test table. This reduces the
breakdown table size about 10% and greatly improves the performance of
querying test names. This update requires running db_upgrade.py and
using the new UDPATE.php and internals.php changes.

In addition, this patch skips the condensing step when we already have a
condense file for a previous month. This improves the update.py running
time by about 50%.
