Emote rework, invalid emotes are passed to ..(), slimes and cyborgs exempt

When an emote fails the switch check for a mob, it calls ..(act).
New files in mob/living and mob/living/carbon with associated procs that
handle these invalid emotes from higher emote calls.
If invalid on mob/living, mob/living will show the invalid emote dialog.
Slimes, Cyborgs, and MMIs do not call ..() on fail.
Start of standardizing required permissions for admins.

Using the dropdown menu / changing health / names of people in view variables now actually requires +VAREDIT.

Shuttle moving moved from +FUN to +ADMIN for convenience sake.

+ADMIN now required to view antagonists / law changes, before it was only required to check antags via verbs, which you could get around through the secrets menu.

+ADMIN Also now required to view all of the special information given about players in who menu (like antagonist status), but all admins can still see stealth keyed admins.
