Support stand-alone ActiveRecord

[aprescott]

I'm attempting to use this gem in a project which uses ActiveRecord in isolation, but it doesn't seem possible due to the if ::Rails::Railtie condition wrapping the code in enum_column.rb. Without this, my schema dumps don't pick up the enum.

This appears to be a work-around:

# require "enum_column3"
require 'enum/mysql_adapter'
require 'enum/enum_adapter'
require 'enum/schema_statements'
require 'enum/schema_definitions'
require 'enum/quoting'
