[Tagging] Snowmobile routes

I agree that route=snowmobile makes more sense. Since there were exactly
zero uses of the tag in the US, I missed it entirely. (Then again, I don't
know how many jurisdictions have numbered snowmobile routes overlaid on the
highway and trail networks!)

Are we agreed, then, on the following?

   - roles should be the same as for route=road
   - name, network and ref should be filled in where available. In general,
   either a name or a network/ref pair is expected.
   - US:NY:snowmobile:corridor and US:NY:snowmobile:secondary are
   reasonable choices for the network

If I don't hear cries and screams, expect a proposal on the Wiki at some
point. (I also haven't abandoned access=permit, just gotten sidetracked on
some actual mapping and haven't got back to it yet.)

Incidentally, US:NY:snowmobile:corridor and US:NY:snowmobile:secondary form
an extensive network of about 15000 km. There's a route map at
http://www.nysnowmobilewebmap.com/webmap/ The numbered routes are in red
(corridor) and orange (secondary). Blue are un-numbered routes belonging to
local clubs. The underlying GIS data that were used for that map are free
for us to use, but I do NOT propose an import because they don't meet my
standards of data quality. Just to begin with, they are digitized at an
inappropriately small scale.
