[OSRM-talk] Bus routes

Currently the demo server only runs the car profile. This is due to how the
osrm pipeline works at this point in time: we pre-process the osm files on
a per profile basis (may take hours).
If we want the user being able to switch between profiles, we have to do
this time and cpu consuming pre-processing for all profiles that we wish to
support.

And because the demo server is, well, a demo server, this would generate
too much overhead. Feel free to do this on your own machine, though :)

That said, we already thought about user-provided profiles --- making it
way faster to change profiles, without the need for heavy pre-processing
--- but this is nothing you could expect shipping in the near future.

In the mean time we implemented features to get the pre-processing time
down for dynamically updating edge weights:
