Add ref and railway:track_ref fields to railway=rail and =switch presets

[gy-mate]

• railway=rail
  • Create ref=* (Line Number) and railway:track_ref=* (Track Number) fields
  • Add these fields to its preset
• railway=switch
  • Create ref=* (Switch Number) field
  • Add this field to its preset

LGTM But disclaimer: I know litte about railway-mappging :-).

Apart from a few minor syntax errors (see below), this looks fine for me as well.

Only one question: the ref field seems to be quite a bit more common on railway=rail objects (see taginfo). What was your reasoning behind putting the ref field into moreFields? Are the track numbers usually easier to map?

[tyrasd]

One more suggestion: As switches only have a single reference number, it would be sufficient to use the generic field for the ref tag, wouldn't it? This would have the benefit of being slightly less effort to translate and maintain. Or is Switch Number a technical term?

@tyrasd Yeah, @tordans suggested this and I agree with him:

railway:track_ref would be commonly known but ref (ref_rail) is something that only external data or professionals would know

Ok, that makes sense now. 👍

@tyrasd Well it's not really an essential technical term. You're right, there is no need to overcomplicate, it's still obvious without ref_switch. Reverted those commits.
