[Talk-GB] Post code map updated with a Code-Point Open layer

[Colin Smale]

Looks really nice, with the colours as well!

Looking at the Thames east of London, the boundary down the river 
between Kent and Essex looks rather suspicious. There seem to be bits of 
Essex with a Kent postcode and vice versa. Is this a function of 
"clipping to the coastline" that you mention? I hope it's not 
representative for the accuracy of the rest of the data...
