Adding the basics of a working TfL Status IA

Added all the files needed to get it working, filled in the basic
attribution metadata etc. The line status API call uses my 3 scale
tokens registered under tim@darkshines.co.uk. Also added a very basic
set of rules to the Perl module to take care of edge cases with lineIds
on:

- Hammersmith & City > hammersmith-city
- Waterloo & City > waterloo-city
- Overground > overground

There's something funny with the API call for DLR which is annoying,
will need to look at that later.
