[Talk-GB] Added Missing Tube Stations on wiki

[Grant Slater]

Hello,

I have updated the London Tube Station wiki page to include a list of 
missing stations. Included the North London Rail Line as it's featured 
on the official tube map and it enters TFL control Nov 2007, becoming 
part of the London Overground network.

Maybe map a few station locations on your way to the London Mapping 
party? :-)
