Language: Consistent use of "frontend"

[michael-wisely-gravwell]

What happens?

The documentation appears to have two different meanings for "frontend":

1. The graphical user interface
   • "Frontend Changes" vs "Backend Changes"
   • "frontend GUI"
2. The webserver
   • "Distributed Frontends"
   • "webserver frontend"

It also contradicts the "webserver frontend" definition by explicitly listing the webserver as part of the backend:

What were you expecting to happen?

"frontend" should be used more consistently or removed in favor of clearer language.
