Report jump: show the target's whole folio, shade its texts too

Browse Source 
Feedback on a real plan: zooming in on the end jumped to was too much.
A jump now shows the target's folio whole, as a page (the view's fit),
selects the target and shades it and its texts blue for three seconds,
so that the eye finds the label too. One function, Element::jumpTo(),
serves the double click on the arrow and on the text.

The mouse pointer is not moved onto the target: Wayland does not let a
program move the pointer.
