adds an share button to map, gallery, and timeline tabs of search results page
adds route for embed views

loadAll on map and timeline embeds. Gallery still lazy loads.
fixed console warning about props passed to share button. the button had two direct descendants, since it had a modal – which meant vue didn't know which child to attach the class attribute to.
