[Talk-GB] NCN refs - consistency

Sustrans, who developed the network, uses 'NCN' as the abbreviation. I 
would prefer NCN25, though I appreciate it is a bit verbose. But if they 
can be rendered in red/blue boxes as per the road signs, then I think 
that would be a reasonable alternative. Mind you, the rendering can do 
that even if the tag says NCN or N or whatever, by simply dropping the 
letters if it knows it is part of NCN
