Releases for Common Object Oriented Library

* Fixed issue #2958120
* Improving code organization
* Adding BaseFormPage, to help having cleaner code when creating PageControllers only to host FormControllers (the page is the form)
* Adding BaseModel, to help creating classes for entity types with EntityDrupalWrapper
* Adding User class(implementing BaseModel), that helps you deal with uses accounts in a much easier way

Development code, not intended for production environments.

After many weeks of use in production, the module can be considered stable, bringing improvement for developers on their daily tasks and not changing the way Drupal works: it's just a wrapper, not a new API.

For the ones using the beta3 version for custom modules, it's import to keep in mind the issue #2310565: $form and &$form_state for Form::build() method, that lead to a change in how forms are handled.

* Small fixes
* Improvements on the API for Blocks and Forms
* Base classes to avoid a lot of empty methods when implementing the interfaces.
