[Talk-GB] Public Rights of Way data for Cambridgeshire

[John Aldridge]

One bit of feedback, from a first try at doing this for real: footpaths 
often cross parish boundaries, and at least in this area change their 
reference when they do so. But your slippy map only displays geometry 
for a single parish at a time, meaning that tracking the prow_ref value 
for the full length of a single path can take a lot of navigation within 
your tool.

Would it be hard to display geometry for all ROWs overlapping the 
current slippy map extent, whichever parish they are from?
