* Added a Form.type_class_map property allowing you to display validation messages with different classes and easily switch between Bootstrap3 and Bootstrap2
* Added documentation of this feature and passing message type in general
* Abstracted error generation to a common template component that is more robust
* Cleaned up error rendering appearance for both Bootstrap3 and Bootstrap2 (fadeIn and fadeOut now :) )
* Fixed a few styling errors with Bootstrap 3 templates, more to come probably
