Redis now saves all output for a task within a hash. This hash contains individual tasks and all its output.
Attempts also start at 1, since that makes most sense for this context. When output is written, the TaskStorage must figure out at which attempt the Task is.
Handlers should now be added as objects, adding some flexibility to the developer.
Developers are still cautioned to take great care that Handlers work approriately. Handlers can potentially crash the SuperVisor if not taken good care of.
Event gets fired when an Event is modified by sending it to TaskStorage::modifyEvent. This allows components to observe changes and report these to the user. Might also be useful to cancel unwanted changes.
