NR5: Docu Popover should include node label

[gregorius]

Hi There,

If the docu icon is clickable in completely zoomed out level (which is good and should be kept) then it becomes difficult to see what the name of the node is, for example this debug node:

So I would suggest putting the label of the node next to the "INFORMATION" title, limited to XX number of characters to avoid overrun (without the red border!).
