[GraphHopper] TurnCosts for CH

[dos65]

Thanks for reply.

I'm as yet in progress to full understanding how CH works. Described 
problem i temporarily fixed by not to call "disconnect" after 
contracting node (i don't know how important it is - in 0.3 was 
"removeHigher2LowerEdges" flag).

Unfortunately we can't afford be yours sponsor, but idea about crowd 
funding sounds good.
Anyway i continue to trying to implement this.
