Implementation of Link

This patch includes the actual implementation of Link, which is
implemented as an extension named LinkBaseExtension in App namespace,
and a full view provider ViewProviderLink in Gui. The reason of not
using ViewProviderExtension is because it need full control when
display, not just extending existing functionalities.

Please see [here](https://git.io/fjPue) for more details of the
implementation.

This patch also includes a set of link manipulation commands, and a
task panel for overriding geometry element colors.
