[GraphHopper] CH vs A*, variable edge costs

[Peter K]

Hey Frederik,

for the normal mode you can use several vehicles. E.g. in the
config.properties do:

prepare.chShortcuts=no
osmreader.acceptWay=CAR,FOOT,BIKE,MTB

Currently the number of vehicles is limited a bit, but we'll rework this
at a later time so that this is unlimited.

Also this should be possible for CH, but requires a bit work:

Peter.
