Ports (and adjusts) Baystation12/Baystation12#12521 et al. Essentially brings our visualnet code up to the standard of three years ago, rather than five.
Side effects of merging may include but are not limited to loss of AI vision, helmet camera failure, garbage collection implosion, infinite turf loops, and unintended layer shenanigans.
High-level changes:
Overall, visualnet/chunk procs have been renamed and refactored to be clear as to their function.
Fix some layering issues related to magic numbers, these have been set to constants.
Visualnets now track source movement rather than overriding individual mob/obj procs.
Adds obfuscation underlay to complicate memory fudging to remove camera static.
Cameras now only add themselves to the cameranet if they're on open (non-restricted) networks.
Helmet cameras now use cameras themselves rather than network defines.
Adds a sorted object list insertion helper.
The Camera MIU (presently unused) should now function properly.
Unused cultnet / cult mask deleted because refactoring that would likely kill the few brain cells I have left
This PR will lead us towards the Promised Day, for in its wake there shall be much celebration and ecstasy as this world becomes a world suitable for developer hegemony. The first strike is thusly;
All << is converted into to_chat().
Ports the rat king from apollo, as an admin tool for now.
The rat king can collect mouse as he walks by, getting stronger, and unlocking some skills, it also can speak to all mouse in the world via a special skill.
