Add task size/priority fields

Changed

Context

With many tasks across different projects, it's hard to know what to work on.

Questions

What should the sizes/priorities be?

What about effort vs complexity?

Ideas

Two vocabularies with freeform taxonomy terms, organized by type.

Example

Size: small, medium, large.
Or fibonacci: 1, 2, 3, 5, 8, 13.

Priority: Immediate, Critical, Urgent, High, Normal, Low, Optional, Deferred, None.
Or sequential numbers: 0, 1, 2, 3, 4, 5, 7, 8.

Terms could have a numeric value to order them.
