Use rasp and fix data handler

[dlrobertson]

• Use rasp for http goodness
• Punt the old data handler
  • Create a data handler thread that bulk inserts at some interval
  • The worker threads now just post their retrieved pages to this list of pages to be bulk inserted with executemany
  • Rely on psycopg2s encoding. Don't try to hand format the insert string.
  • Remove MongoDB stuff
  • Remove wierd exceptions
• Remove old codez
• Re-License to a more liberal license (BSD)

This is far from complete, but this removes a lot of old stuff that either doesn't work or is super fragile. After this 60% of the time it should work all of the time.
