* Removed Heartbeat timer 

* Implemented a proper update thread
* Removed the UpdateLock Mutex as it's no longer needed because updates can only happen one at a time now.
* This should actually improve performance significantly.. But, see the warning on the next line!
* Warning: If there are deadlocks that the threadpool timer method was hiding, this will expose them for all the nastiness they are.
