Now uses sqlalchemy for persistent storage and logging.

* Uses sqlalchemy declarative schema for the log and saved URLs.
 * runbot now not using nohup. Will need to be daemonised somehow.
 * Refactored botcommon.py out of existence.
 * Now reads from a config file which can optionally be specified at the
   command line with --config option.
 * Prints usage with --help or if no config file is found.
