Improvements made to the gaming registration devices modules
- Ability to enable/disable the module
- Category assigned to the registered devices in pf.conf
- Review code structure a bit

What's left to be done:
- Review most of the lib/pf/web/gaming.pm methods compared to lib/pf/web.pm and see
why there's duplicate and avoid theses.
