IVB moved to mobile HAFAS and fahrplan.ivb.at

[simon04]

The new website is https://fahrplan.ivb.at/webapp/?L=vs_ivb and can be accessed using the AbstractHafasMobileProvider. It uses the API version 1.20 and some adoptions had to be made:

• maxDist is required for jsonLocGeoPos
• stbFltrEquiv and getPasslist do not work for jsonStationBoard
• I refactored the JSON response parsing and error handling to parseJsonPage.

The PRODUCTS_MAP should be reviewed; I copied it over from VvtProvider.

Fixes #183.

@schildbach: can this pretty-please get merged in? the öbb suggestions often don't find the station i'm looking for and having the broken innsbruck provider in the menu has confused a lot of friends i've suggested the öffi app to.

So it seems the IVB has moved to VAO too. The problem with that is the VAO is threatening to sue anyone using "their" data. That's the reason most of Austria isn't in Öffi anymore.

@everyone: Is any other user of public-transport-enabler interested in getting this merged?

I'd take it. Better to have working code with legal risk than no working code at all.

I should add that most likely what fahrplan.ivb.at provides is identical to what VvtProvider (Tyrol) already has access to. Or VaoProvider for that matter. All the fahrplan.*.at domains seem to point to the same VAO-run server.

If you still think the new IvbProvider is useful then I propose to split it up into two commits (or PRs). One just adds IvbProvider but doesn't move the API to version 1.20. I'm almost sure it will work. Then another one raises API version to 1.20 for all VAO-based providers.

@simon04 Please let us know once you find out how to support the stbFltrEquiv and getPasslist features again with 1.20!
