Started work on unified Request/Response system
- when finished, plugins will send request the same way on master and workers, this should simplify the code and enable multiprocessing tools to be pickled and depickled on the master
Completed work on unified Request/Response system
- requests to handler are now sent via NetWork.request.sendRequest both from workers and from master, there is no need to use Workgroup.sendRequest
- responses are now handled easier, they can go from a handler to a function on the master, that wasn't possible before
- plugin code is simplified because of the simpler request system
- death handling code is now in Workgroup.dispatcher, this avoids redundant error checking code in handler functions
