Feature request: `partition` command

[benj-dobs]

I might have time to work on this at some point if you guys want this. I think it would be a nice little speed-up feature if there were a 'partition' command. So:

• t out --at "2 hours ago"; t in --at "2 hours ago" New task
  becomes
  t partition --at "2 hours ago" New task

• t edit --id 123 --end "5 Dec 15:00"; t in --at "5 Dec 15:00" New task; t out --at "5 Dec 17:00"
  becomes
  t partition --id 123 --at "5 Dec 15:00" New task

This adds nothing to what timetrap is capable of, it would just make it slightly more pleasant to use, for me anyway :)

I thought about this feature with a different approach (because my use case is for archive) in which you can archive certain amount of time, splitting an entry if needed. What is your use case?
