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.

Some refactoring of how handlers are handled, particularly with their default options. This is an unfortunately widespread change and will affect modules utilizing the API.

#252970 by eaton and #250516 by RoboPhred: More stuff for statistics.module and default views for popular content

Initial statistics implementation (by eaton). Also last commit was by alpritt (forgot to enter it on that line, so you get it on this line)
