- Renamed the class veil to fhc-ajaxclient-veil in AjaxLib.css

- Added new classes to AjaxLib.css to configure the new error dialog box
- Adapted AjaxLib.js to use the class fhc-ajaxclient-veil
- Added a new private method _defaultErrorCallback to AjaxLib.js
- Now if an errorCallback function is not given when AjaxLib.js is used, then _defaultErrorCallback is used as fallback
