#130 - Moved the usage of omit_id_generation to id=nil
* The class_eval action_view_extension.rb was being used to omit id generation for fields. Since ':id => nil' does the same task, replacing omit_id_generation with that.
* Have added tests in few places. Didn't add tests for partials where new spec files were required to be added as it's a very small change.
#130 - Deleted the class_eval action_view_extension.rb and its spec.
* The action_view_extension.rb was used to provide omit_id_generation tag to omit the generation of id for the specified field. The usage of omit_id_generation has been replaced with ':id => nil' which does the same job of omitting the id from the specified fields.
* This class also provided the to_check_box_tag with the ability to remove the hidden field tag from the field if required. This tag is no longer valid in Rails 4 and is not being used in the migrated classes.
#130 - Incorporating the Hound's feedback.
* Using Ruby 1.9 hash syntax and added missing spaces around the braces.
Revert "#130 - Incorporating the Hound's feedback."

* Reverting the commit as inlining of partials wouldn't happen if Hound's feedbacks are incorporated.
#130 - Removing the puts which was pushed upstream by mistake.
#130 - Changing to new Ruby 1.9 hash syntax in the specs.
