Now uses the new API instead of attempting to combine the picasa and drive APIs.
It uses parallel processing for fast downloads.
Now fit for running in the background with cron. Fast indexing when no changes have occurred. Exits cleanly on sigterm Single instance only allowed for each root folder (further instances exit with a message and no error). Fixes for #16 #11 #17 #15 #14 #7
