#19 New gadgets

[lenz73]

We should have two more gadgets on a page:
- print
- permalink

Print should be a little printer, and should print the page
(by using CSS, the toolbox should not be printed, like in
basic.osk)

The permalink should point to a full URL like http://www.
pangea.va.it/index.php?n=86, that is shorter that the fuill
name and better suited to copy-and-paste
