[openstreetmap/openstreetmap-website] add link to open view in OSMCha, from changesets history pge (#2629)

[Seth Deegan]

If OSM doesn't want to link it, then I think development of better Changeset analysis tools needs to happen. 

**Possible changes:**
- Changeset changed element geometries should viewable (like OSMcha)
- When you click on an edited node/way/relation in the list for a Changeset page, it shouldn't bring you to page for that element, but rather a page that compares the previous and next Version of that element from the Changeset. 
- The the Version comparison should show changed geometries of elements (like OSMcha).
- The the Version comparison and All Versions page should **highlight** the changed tags of elements (like OSMcha).
- The "View History" link should not be tucked at the bottom of every element page next to "Download XML". It's barely visible.

Also, new mappers don't even know what OSMcha is.
