Adds the pool_recycle option to the sql engine startup call.  This enables connection auto-timeout so that connection pooling will work properly.  The recommended setting (per sqlalchemy FAQ page) has been provided as a default for a new configuration flag.  What this means is that if a db connection sits idle for the configured # of seconds, the engine will automatically close the connection and return it to the available thread pool.  See Bug #690314 for info.

The fix was tested and verified on multi-node deployments of Austin and Bexar with MySQL, and it was also verified that the change does not affect sqlite users (dev environment testing only).
