#89 update "collected by" field in sidebar collector

[Bethany Nowviskie]

It would be nice if the "collected by" field would update just like the "browse tags" field does when you collect an object within the sidebar.

Jamie reports: "When I collect an item in the sidebar, "collected by" is updated." -- but this isn't the case for me, not until I manually refresh the page, whereas the "browse tags" one updates automatically.
