BRouter trekking: avoid fords / grade5 tracks / bad-visibility trails by default

Routed through icy fords and abandoned descents 3x. Penalise ford nodes & ways
(ford=yes|stepping_stones), tracktype=grade5 and trail_visibility=bad|horrible|no in
the trekking profile, gated by a new %allow_adventure% param (default false = avoid).
Both profile copies (asset + staging) kept in sync. NOTE: profile syntax must be
verified by routing on device; a bad profile makes routeBrouter error out (safe), not
produce bad routes.
