[project @ Moved ga_frontend to gaworkflow.frontend package.]
 * All the modules in the front end have been updated to be
   located in gaworkflow.frontend.
 * Requires that PYTHONPATH include top level directory or
   for the package to be installed as gaworkflow/frontend/manage.py
   only adds frontend/ to the python path, and therefore it will fail.
 * Changed the hard coded paths to be more like
   os.path.abspath('../../fctracker.db') so, the code should just work
   if the main package is available on the python path. (Good defaults
   are nice!)
