[Merkaartor] A few requests

[Matias D'Ambrosio]

 A few things I'd find useful:
  Please integrate the patch that adds a white background behind the scale 
(1km, etc), until it can be replaced with a nicer method.
 "Select all nodes belonging to this way" would be nice to have.
 When editing a relation, if one clicks on an item (to change the role, for 
example), it would be useful if it were highlighted.
 When an item is selected, it would be nice to have a "relations this item 
belongs to". When multiple items are selected, it should show the relations 
in which they are all present.
 When one presses enter to accept the edited role, the cursor should go to the 
next item's role.

 Now I'm off to lunch and learning to use trac for bug/wish reporting :-)
