Code review comment for lp://staging/~pickscrape/bundlebuggy/escape_quotes_on_my_todo_page

A colleague (who has an apostrophe in his name) today discovered that the "My Todo" tab would crash for him with a backtrace.

This branch fixes the problem by escaping apostrophes in the submitter name before it is passed into the querying objects. A better fix would involve parameterization, but my available time limited the amount of framework learning I could do in order to get this working.

Hope this is of use.
