Ghosts can now text communicators in round, and can be texted by those back.
This is obviously logged, just in-case funny business occurs.
Adds verbs to display a log of messages that a ghost has sent and received, as well as a verb to send a message to a communicator of their choice.
'chu heard me. S'what it does. When you're on a call, there's a "Start Video" button next to each person. When you click it, you actually look through their thing, like a ghost might if they ghostcalled. You have to stay within 1 tile of a video showing communicator to see it.
Multiple people can share one communicator video stream by setting it on a table or whatever, and examining it. There's a message like "It appears to be showing a video: [view]" and you can click view and you can all look at the video. COLLABORATION. SYNERGY. OTHER BUZZWORDS.
I also added the feature of DECLINING requests from people.
Also communicators show up on a special camera list on security consoles, but the same EPv2 network visibility turns this off as well if you wanna be all hidey. This does mean that people with the visiblity on serve as sort of roaming AI cameras for the AI as well. So the AI can watch you repair the outside of the station or whatever if you want.
``/mob/dead/observer`` -> ``/mob/observer/dead``
``/mob/eye`` -> ``/mob/observer/eye``
Reason being that they are similar in that they both don't interact with
the world in any way. Some procs were shared, some checks as well, and
it overall makes more sense this way. Plus, there were no ``/mob/dead``
mobs.
Fixes exonet node research pattern being wrong.
Makes communicators showing up on the ghost communicator list have stricter checks for being able to receive a request.
