App icons: Remove unused, rename misnamed icons (#273)

Gnome Settings now uses a text-only list and incorporates
power, session, display, and sound (and more) related settings.
So these icons are no longer needed. I checked Adwaita history
before removing these and was able to find deprecation info on
almost all of them.

Some of these were linked from or to the `categories`,
`actions` folders as well as the elementary-xfce-darker
variant folder so icons in those locations  were
re-symlinked/moved/removed when needed.
