* update params structure for OSM iD

update params structure for the iD editor hosted at openstreetmap.org/edit : have to keep the params after a # instead of ?

* working osm editor with-gpx-hash-param link

* update list of query/hash params on osm.org 

Some hash parameters are not supported on osm.org, while there are some query parameters which work slightly differently when used on osm.org 
See https://github.com/openstreetmap/openstreetmap-website/blob/66656e1d1d58e6073efd453007d7452920531b37/app/assets/javascripts/edit/id.js.erb
