Linus Groh 47d7faa998 LibGUI: Update active tooltip when source widget changes the label ...

Application::show_tooltip() now keeps track of the application's active
tooltip source widget so it can be updated while being shown when the
same widget updates its tooltip label.
Application::hide_tooltip() will unset the tooltip source widget,
respectively.

This is pretty useful for the ResourceGraph applet's tooltips!

Also re-use the Application::TooltipWindow's rect position in its
set_tooltip() method to avoid flickering from the window temporarily
being moved to 100, 100 and the position adjusted moments later.
