Some worker config stuff
Tasks dont change storage_data
Error handling in Remote commands
Pass whole input file name and path to action_caller instead of only path
Error in dataset or part from earlier jobs lead to rejecting tasks
Workers return list of files they created. This way if they are many, master can pick them from e.g. a workdir
Missed an argument in setting workdir db calls
Stripped out some tasks which I will work later on
Removed instance state variables self.part and self.dataset, since they should not be shared amongst celery workers.
Wrote an empty finish method and some comments
Some bugs
Left the self.runtimerrormail in favour of setting it in action_caller. No possibility for users to define now, but now becomes possible to add filenames and worker names, don need users to mess with format strings.
