HTML Widgets and Portals; Angular-style data binding; Now show 'undefined' object properties as a blank string

Using angular style tags to bind to object properties displays "undefined" if the property did not exist, e.g.:

<td><label>Phone</label><div ng-bind="mRecord.PhoneHome"></div></td>

Binding is achieved by calling the widget.UI.Evaluate() method.

"undefined" values are now displayed as blank strings.

This applies only to the following attributes:

• ng-bind
• ng-bind-html
