/*

Generates each row in the contributions list.

Contributions which are marked "top" are currently on top of the history.
For these contributions, a [rollback] link is shown for users with sysop
privileges. The rollback link restores the most recent version that was not
written by the target user.

If the contributions page is called with the parameter &bot=1, all rollback
links also get that parameter. It causes the edit itself and the rollback
to be marked as "bot" edits. Bot edits are hidden by default from recent
changes, so this allows sysops to combat a busy vandal without bothering
other users.

TODO: This would probably look a lot nicer in a table.
