SRTShortcuts: menu item for comments_trafficjam layer
addition of comments_trafficjam

Now fully editable, checked in data/Makefile and part of MANIFEST, but
still not selectable as a layer (except in the SRTShortcuts plugin).
BBBikeAdvanced: penalty for streets with traffic jams
no actual change, just adding scopes
obey directions for tram penalty
replace a POSIX::tmpnam usage (and modernize code a little bit)
Geocoder plugin: LocalOSM now available only in devel mode

Problem ist that the require check is done too late, not when
rendering the radio buttons. The temporary solution is too make this
option visible in devel mode only.
add Geo::Coder::{Bing,OSM} to future windows distributions
data update (minor)
