Make new Images/InterfaceSetup directory, move images
When you create images in wiki pages by pasting them into the Github
web interface, they go in as "user-attachment" assets, where it
becomes difficult to manage them *and* they aren't actually part of
the git repo. A user who clones the wiki to have an offline copy of
documentation would not get those images.
I have downloaded all of the images that were on the
"Interface-Setup.md" page and put them into Images/InterfaceSetup.
I've been doing most of my wiki editing locally on a git clone, not
through the web interface, which is pretty much the only way to manage
directories and image files.
Every interface's properties are fully documented in pages for that interface type, and they're all linked to from Interface-Type-Dialog. It's not that "basic documentation" can be found there.
