The attached patch adds an additional layer to the resultant SVG containing the start of a RelationRoute solution.

The layer is controlled by two variables in the map-features-file:
showRelationRoute = ['no' (default if absent) | 'yes' | '1234' (specfic RelationRoute with ID '1234')]
showRelationRouteFade = ['no' (default if absent) | 'yes' (100% fade - ie underlying map invisible| '0.0' (no fade) through '1.0' (100% fade)]

At present the ways on the new layer do not have any style and thus render a bit funny, so I would appreciate any suggestions. Ideally this could/would be controlled from the map-features-file, using any of the RelationRoute tags (route, name, ref, network, operator, etc).

Any objections to me checking this into SVN?
Cheers,
Simon.
