[Tagging] network tag on route relations

Sounds to me that the scheme is creating a problem rather than solving
it... requiring a lot of prior knowledge and tables to code, and expert
knowledge and tables to decode. If anything, I would want to make it
simpler, not more complicated.
Anyone who wants more consistency, please map all Dutch recreational routes
onto the new consistent scheme without breaking current rendering and
processing, if you can do it, let's talk again!

Disambiguation.  US:FS:Hood and US:FS:Ozark are two different national
forest service networks with entirely different numbering schemes.  Plus
network=CA by itself would be Canada, not California, which is US:CA...
