Issue 2179

http://code.google.com/p/otwarchive/issues/detail?id=2179

This fix will collapse user kudos after 50, replacing with "and x more users" in the kudos list and adding a button to the bottom right reading "See all kudos." Clicking on the button replaces "and x more users" with the full list of users who left kudos, and adds a "Collapse kudos" in place of "See all kudos" that restores the original state.

Needs testing for non-javascript browsers to make sure everything degrades gracefully. If there is no javascript, the list should always appear expanded.
