Fixing file permissions on mrc2png after editing on Windows.
Changed "Process" into "Tasks" along with a fundamental change in how they are implemented. Instead of creating a process that is dependent on other processes you now say which inputs and outputs each task has and the rest is figured out automatically. The Tasks class knows about all of the tasks instead of just itself which simplified other parts in the code greatly along with giving greater power and easier to use.

Some other minor problems were fixed as well.
