Route: Redesign command output

Browse Source 
* Route flags now single characters to save
  space.
* Align addresses to columns based on maximum
  size of family address. We can easily pre-loop
  over routes at a future date and choose
  the smallest address width if needed.
* Moved interface device to last column as width
  can vary a lot.
