Added MetroScrollBarRenderer which supports MetroLight and MetroDark color schemes.

Added MarkupLabel.LinkColor and MarkupLabel.ActiveLinkColor properties to determine the default color of link elements when explicit colors are not defined by the anchor element.

Updated Microsoft .NET Framework 4.0 targets to .NET Framework 4.6.2 since it is the most recent supported version of .NET Framework.
