Develop

Main points:
- DB queries abstraction
- Isolate CURL requests from openCPU model
- major Code formatting (views)
- Run view removed from Model class (run contents are not returned from Model to controller and view loaded from controller)
- Cron should run as stand alone PHP script and crontab in /config/formr_crontab should be placed in /etc/cron.d/formr_crontab (this will hopefully reduce curl request time)
