Title: prefer extend over include

The previous method of adding enumerize to a class was deprecated. So
intead of:

include Enumerize

please use:

extend Enumerize

This prevents adding extra constants from Enumerize module (e.g.
Enumerize::ActiveRecord, Enumerize::Set) to the extended class. The
corresponding top-level constants can be accessed without using
top-level qualifier `::` now.
