issue #1953 improved privacy on searches and associate each search to its creator

* remove temporary functions ws_gallery_getSearch and ws_gallery_updateSearch
* split get_search_array into sub-functions to use them in web API
* use search_uuid as search_id instead of the numeric search.id : better privacy
* only the creator of the search can update it
* if a visitors tries to open the search of another user, it (the search) gets forked into a new search
