[Talk-GB] Postcodes again

[Dave]

I've updated the postcode map I created, and it has a new home on dev too:

http://dev.openstreetmap.org/~random/postcodes/

There's now a whole selection of layers available, representing
different post code sources. Click on the + to select between them.
The layers are:

NPE -- postcodes collected from the npe map site
FTP -- postcodes collected by freethepostcode.org
OSM -- postcodes extracted from the latest planet dump. Post codes
specified with the postal_code tag are pulled from nodes, and ways --
there's some development that needs to happen regarding pulling post
codes from ways cos I think it's a bit buggy at the moment.
All -- the above three sources merged together into a single layer.
This is the default layer and /should/ be the most precise.

The layers are set to update twice a week for the NPE, FTP and All
layers, and once a week (sometime after the planet gets released) for
the OSM layer.
Hopefully this will encourage everyone to start collecting post codes
on their travels if they haven't been already.

Enjoy!
