The float item should

- show the current content of the short license description

- honor the attribution never/always/opt-in/opt-out settings

- on click on the short description, show the long description instead. The size of the floatitem needs to adapt accordingly. A click on the long description will toggle back to the short description.

- Weblinks need to be clickable and need to invoke a browser with the current Url.

- FloatItems should have default menus like "Lock" and "Hide". "Hide" should be disabled on "Always".

- The semitransparent background should be deactivated by default and the text should be rendered outlined (like for the Edit/Print map)

- There should be a menu entry to open the about dialog.

(some of these things have been partially implemented already)
