HTML Widgets; Intellisense bulked up to work with Widget controls

HTML Widget intellisense now works (with some limitations) for Widget controls, e.g.:

var cboTest = widget.UI.DBCombo("cboTest", {});

cboTest.RefreshFromStandardRange(

Typing the dot after cboTest now lists (providing they are documented in the widget Help file), methods of the widget DBCombo control. Also, adding an opening bracket to RefreshFromStandardRange lists parameter information.
