Improve workboard "Owner" grouping, add "Author" grouping and "Title" sort
- Put profile icons on "Group by Owner".
- Add a similar "Group by Author". Probably not terribly useful, but cheap to implement now.
- Add "Sort by Title". Very likely not terribly useful, but cheap to implement and sort of flexible?
