clean up and refactor half-baked development commits and squash them into a new version.

Changes:

* support for multiple GTFS feeds as input in filtering, read default global and local configuration files
* be a bit more memory conservative
* make caching optional
* dont delete orphan edge if it would transform a degree 3 node with a possible full turn into a degree 2 node eligible for contraction
* dedicated filters for funicular and gondola
* make max snap level option more intuitive
* allow filter rules for level 0
* additional fallback for station snapping
* dont try to route for MOT unequal to trip in -T mode, force-snap to orphaned OSM station if not snap was possible
* write bounds to filtered osm
* remove unused surrounding heuristic
* use bus lanes info
* be a bit more tolerant for bus oneway streets
* create missing directories
* error if no cfg is present, clean up evaluation Makefile
