Version 0.9.19b3. The simulator thread can be paused to be able to add and delete simulators. Added simulated door and PSU status. Devices can now fully use multiple simulators. Better rounding of simulated temperature values. The server SIMULATOR DEL and ADD commands pause the simulator when the linked list is manipulated. Fixed SIGSEGV when a simulator is added. Added socket SO_REUSEADDR again to the server socket.
