#368234 by dww and neclimdul: Allow the "Anonymous" user to have a different (or no) name in User: name field.

#349178 by agentrickard: Add generic link handling plus a custom text field. Also automatic trimming.

Major re-organization of handlers. PLEASE NOTE: This drastically affected the Views module API and until modules are updated to match, they will stop working. Efforts have been made to ensure that this won't cause your site to crash, but that's partly up to the individual module as well.
