typ file changes

* reversed mount symbols (for slopes)
* mount symbols with question marks
* changed ids from 0x4. to 0x14.01 (otherwise it was not properly
  displayed on the garmin)
srt-style changes: use mountclass
new bbd2osm experiment: mount support
data update (systematic ferry information update)

Also transformed most "by" directives into "url" directives,
for visibility in bbbike.cgi's route list.
cgi: URL information also for ferries
cgi: bugfix: add comments_ferry to comments net only once

The previous code used to add comments_ferry twice, once with and once
without UseLocalDirectives enabled. So it was pure luck if a url
showed up or not.

The code around this change was also simplified to have only a flat
MultiStrassen object.
cgi.t: fix because of changed data

Changed tariff information for F11
data update (minor)
new test bbbikebuildutil.t
travis: use correct freebsd-compatible make

By calling BBBikeBuildUtil::get_pmake.
