leaflet: changed geolocation implementation for more data

The original Map.Geolocation.js was duplicated into bbbikeleaflet.js
and members/methods renamed to avoid conflicts with the original. The new
my_locate provides all data from the browser's geolocation object. The
upload functionality is using timestamp, altitude, accuracy, and
altitudeAccuracy. Additionally, the lat/lng precision is now cropped
to six digits after decimal point, to make the upload size smaller.
rawjsontrk2gpsman.pl: convert also altitude and timestamp

The new members alt and time are now also converted, making the gpsman
format complete. Additionally, the timezone information is now taken
from the local time, and a dummy track title ("ACTIVE LOG") is created.
leaflet upload: send also UA, and add it as comment to the gpsman
output
leaflet: call removeLocation() if location tracking was turned off
data update (minor)
