Allow oneway=-1,1 only (#1267) 
This PR removes cases of `oneway=0` as this is an assumed default.  It is not necessary to have this tag on every road or path and by removing it we can save space in the tiles by only including the meaningful values.  It leaves intact `oneway=1` and `oneway=-1`, the latter of which indicates a oneway in the opposite direction of the way.
