route description for paths without names

[emiltin]

the route description needs to be different for ways no names. as it is now, odd descriptions result:

1. Head on Njalsgade for 80 m
2. Turn right on for 89 m <--------------- odd grammar
3. You have reached your destination

i'm also noticing that turns from a way without a name, to another way without a name seems to be excluded altogether from the route description. for example this route description is output for route that in fact includes 3 turn (at path intersections):

1. Head on for 352 m
2. You have reached your destination

an idea could be to use the type of path in place of the name, for example: "turn right on cycleway", "turn left on footway", "continue on residential road", etc.

Good catch. The issue with turning from an unnamed way into another one needs attention.

[DennisOSRM]

This is implemented now. The output will announce every possible turn at junctions of unnamed streets in the hope that the number of those streets is rather limited. That assumption holds at least for western Europe.

Will push later today to master repo.
