feat(view): -VIEW orthographic UCS, sEttings and Window like the reference

An orthographic preset sets its orthographic UCS while UCSORTHO is on
(*FRONT*, *RIGHT*, …; TOP returns to the world UCS); presets no longer
flip to the opposite view when repeated. -VIEW runs as its own command:
Window asks for the name and corners, sEttings loops over Background,
Categorize, Layer snapshot, live Section, Ucs and Visual style with the
reference prompts and messages, Save keeps the UCS with the view while
UCSVIEW is on and Restore brings it back. UCSORTHO and UCSVIEW are
profile variables.
