Add a command that could enable/disable the viewing of the host while in photomode.
Something like: /gs viewhost disabled/enabled

There's currently an option that allows you to hide all players, so it would be like that, except it's for a single person and is forced.
(so in photomode you'll be invisible to other players)

This is to help track devs complete their tracks without people watching them in photomode to see how it's done (for tricky tracks and/or for tracks with shortcuts)
