HTML Widgets; New method, widget.UI.SelectFlagColour

A new widget.UI.SelectFlagColour method is available for use in HTML Widgets.

This prompts the User to select a coloured flag, e.g.:

widget.UI.SelectFlagColour(null, {}, function (colour) { window.alert(colour)});

widget.UI.SelectFlagColour("Red,Blue,Green", {}, function (colour) { window.alert(colour)});
