Settings and activity

Seems very similar to my suggestion of being able to "skip" tasks (i had in mind recurring, but it wouldn't have to be). Should we combine these two feature requests?

So if we cancel a task, the info is retained, but it no longer shows up as being due or overdue. For recurring tasks, the next ocurrance would still be due at the normal time.
