* bbbikegooglemap.cgi -> use gmap v3 api
* flag shadows work
* simple copyright functionality for gmap v3
* renamed bbbikeorg -> bbbike_mapnik
gmap v3: translated openInfoWindowHtml call
gmap v3: translated geocoder
gmap v3: fixed setwptAndMark

google.maps.Marker call was wrong
gmap v3: fixed polyline drawing (route upload or search result)
bbbikegooglemap.t: adapted check_polyline for new "var path" variable
gmap v3: change order of custom map buttons, to match the v2 version

That is, it's again [Mapnik] [Cycle] [BBBike], not [BBBike] [Cycle]
[Mapnik]. This may be changed later again, but now it's good for
(automated) testing to have it the same order.
bbbikegooglemap.t: test is now compatible with v2 & v3
bbbikegooglemap.cgi: conditionless switch to v3

Google switched some days ago the v2 API to a wrapper around v3. Since
then some things were not working anymore, e.g. marking the goal point
for search or selecting more than one point for a custom drawn route,
so I was forced to switch.
Merge branch 'gmap-v3'
