Sam Saffron a8fbb19e7c FEATURE: allow a huge number of users to share common prefix
Previously username suggester would give up after 100 attempts at getting
a username and fallback to random string.

This amends the logic so we do all the work of figuring out a good username
in SQL and avoids a large amount of queries in cases where a lot of usernames
were used up.

This corrects an issue on sites with large numbers of anon users
