Scheduler Improvements

[Chris-Kellett]

At the moment the FakeYou checks are holding up the rest of processing in the Scheduler.

• [x] Store the last time the FakeYou models were checked in the Database
• [x] Have this value propogate between re-deployments
• [x] #94

The last point seems key, shouldn't all tasks spawned by the scheduler be in goroutines?

[Chris-Kellett]

Yes it should, done all tasks in attached branch.

Solved the last issue by use of a mutex to the "SaveJson" function which is used by the dashboard.
