Compact pre-Grizzly database migrations.
Compacts the pre-Grizzly database migrations into a single migration (133_folsom.py). Pre-Grizzly users will need to upgrade to Folsom before running any Grizzly migrations. Tested on PostgreSQL and MySQL schemas on Fedora 17 to ensure the new compacted migration generates an identical schema to the previous migrate scripts in Folsom.
