Database reorganization

Today my new research assistant Gavan & I are performing some maintenance tasks on the database, including a reorganization of the places where the data tables live. Hopefully this will mean that the data is much better organized.

Here is the github summary of what we are doing, and a brief summary below.

We will leave old copies of the most popular tables for a few days, in order to give everyone time to rework scripts, etc.

Renamed:
sf database to 'sourceforge' (remember this is only pre-2009 metadata)

Moved:
OSSMOLE_MERGED SCHEMA
al_* tables to 'alioth' schema
fm_* tables to 'freecode' schema
fsf_* tables to 'free_software_foundation' schema
gh_* tables to 'github' schema
gc_* tables to 'google_code' schema
lpd_* tables to 'launchpad schema
ow_* tables to 'objectweb' schema
rf_* tables to 'rubyforge' schema
sv_* tables to 'savannah' schema
tig_* tables to 'tigris' schema
