Description

Add a filter for learners (newly autoconfirmed users)

Put the user's experience level in the DB as a string rather than
as a learner/not-learner boolean, so it's easier to add filters
for e.g. experienced users in the future.

Bonus: actually run PageTriageTagsPatch.sql from update.php
