Add support for validation feedback.

Model and property validation results are now passed on to the AdminAction feedback system.

Changes:
- Added ‘AbstractSaveAction’ which holds all common methods and features between ‘SaveAction’ (Create) and ‘UpdateAction’;
- Revamped XHR request in form.js and quickform.js to better handle errors and processing of feedback;
- Improved output of feedback in dialog;
