[Talk-GB] C roads

[MarkS]

Sometimes though the reference is in general use even if it isn't 
signposted. In this case having it on the renderers might be useful.

For example: we have a C road near us. On the ground the road looks like 
a single road, but in reality it is made up of series of roads with 
around 6 individual names.  For simplicity therefore lots of local 
publications (magazines, political flyers, local websites) just use the 
C reference.

Having the reference on renderers is therfore useful.

That said I've seen a mapdust error that the reference wasn't signposted.
