Initial port of Competitor/Member code from UDA
Add scores, judges, db, models and model_specs
add all the scores controllers, libraries, tests, and views (views are untested)
Reorganize the abilities class, to allow for judge ability, chief_judge, and also reduce duplication
Reorganize menus, adding entries to allow judges to see judging menus, and ability to manage chief judge (among other abilities).
Add option for creating judges (full-stop), and also for associating judges with event_categories. Had to move chiefs around for this
