Adds a MAPTEXT macro that wraps the given text in the maptext class, the thing we use for Runechat to make it so you can actually read it. Everything that sets maptext now uses this.
Previously your chat messages would be obstructed by the blackness of blocked turfs, aswell as dark lighting and some other effects. This fixes that
It still has backdrop ambient occlusion like it used to.
Adds SIGNAL_HANDLER, a macro that sets SHOULD_NOT_SLEEP(TRUE). This should ideally be required on all new signal callbacks.
Adds BLOCKING_SIGNAL_HANDLER, a macro that does nothing except symbolize "this is an older signal that didn't necessitate a code rewrite". It should not be allowed for new work.
This comes from discussion around #52735, which yields by calling input, and (though it sets the return type beforehand) will not properly return the flag to prevent attack from slapping.
To fix 60% of the yielding cases, WrapAdminProcCall no longer waits for another admin's proc call to finish. I'm not an admin, so I don't know how many behinds this has saved, but if this is problematic for admins I can just make it so that it lets you do it anyway. I'm not sure what the point of this babysitting was anyway.

admin: Calling a proc while another admin is calling one will no longer wait for the first to finish. You will simply just have to call it again.

Changes the object runechat text is overlayed onto from the talker, to the closest thing to the turf the talker is in.
This means if someone is talking in a locker, you can see it. Ditto for radios in people's packs.
