Poke emailing an item.
Add some more tests to boost coverage.
URLs in help pages didn't have quoting around them. Found this when adding tests for help pages.
Also add tests to exercise editing the user profile.
Comment out what I believe is dead code, since we add people to items by creating itemperson objects instead,
Might help if we actually call the test methods by the right name.
Also, fix typo in fetching the user profile.
Tests for add_tags() and the "Fill Slot" functionality.
