Users should have the option of manually chunking tasks

As a last resort, users should be able to manually chunk tasks themselves.

In addition to manually chunking tasks (presumably in the task modal), users should be able to manually assign certain chunks (and have others be automatically assigned). This necessitates a chunk modal.

This will probably require some architectural changes. Tasks will likely need to have some conception of their chunks; right now, chunks are completely independent of their tasks and are handled exclusively by the central store.

A possible issue is what happens when chunks are scheduled manually but the task is edited. For example, there could be problems if the user manually chunks a 3-chunk, 60-minute task and then reduces the number of chunks or the duration of the tasks. There are several possible solutions to this problem and I will deal with it when the time comes.
