Journey and Rails 4 are going Separate Ways

Journey was merged into Rails: https://github.com/rails/rails/commit/56fee39

Also, activerecord-deprecated_finders is not necessarily explicitly bundled here
because it would be bundled through rails' dependency for now, and we're not using it in Haml's tests anyway
The TextArea hack should be loaded under Rails 4 as well...
Rails 4 does not render default cols and rows options for textarea

see: https://github.com/rails/rails/commit/3384ee2
