Field of Vision component. (#12075)

* Hopeless WIP for vision cones. * Core component and hooks done * Removing clutter. * linter bashing me for using statements as args. * Ok. * continue * bring back the macro * Configs and openspace filter. * Chat plane, reset perspective signal, mechs/vehicles cases, machineries. * view, viewers and spoopy ghosts. * Renamed component, admin fun button and snowflakes robots. * Whoopsie. * Yikes * test merge tweak. * radial yaketi sax. * Fixed tgui UIs, some messages not displayed to the target. * Documentation and a little bugfix. * Pulling QoL, seventh plane made in this PR. * Fix. * Tweaks and improvements. * Update randomverbs.dm
