* Adds SIGNAL_HANDLER and SIGNAL_HANDLER_DOES_SLEEP to prevent signal callbacks from blocking (#52761)
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.
Requested by @optimumtact.

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.

About The Pull Request
Non-taggers' graffiti counts as bad art. Taggers' graffiti counts as good art, not great art.
Makes the art defines global defines and removes some magic numbers.
Re-orders the switch statement for art to go ascending instead of descending, because otherwise if something is at BAD_ART it will register as good instead, if it's at GOOD_ART it will register as great, etc., which defeats the purpose of having defines.
Why It's Good For The Game
The tagger component: Because there isn't really much bad art in the game ,and graffiti is as obvious a candidate as any, and gives the janitor an actual excuse to remove it besides being a dick. If you don't want the potential for a bad moodlet, don't examine the art. You have to go out of your way to do so anyway.
Very slightly nerfing tagger graffiti: Because "what a thought-provoking piece of art" is kind of much for graffiti.
The other component: Because there's no point in having defines if people are just going to put magic numbers everywhere anyway. (I left the impressiveness numbers for statues, etc. alone, because those can take damage, dropping their quality. But if something can't take damage, just use the define.)

About The Pull Request
Adds 'notice' span class to all visible_messages which had no span class, making all those black messages blue.
Why It's Good For The Game
This should help differentiate action-messages from talking-messages in the chat. More actions will be blue, thus black talking-messages should pop out more.
