Adds support for transparent enums to ActiveRecord.
Adds a belongs_to_enum to ActiveRecord that takes an array of possible values.

Adds an add_extra_data method to ActiveRecord that invisibly includes an extra data table. Use with STI to keep your database clean. It removes the need to have lots of nullable columns.
