Basic usage of blend_mode

Areas - fire and party alarms look better
Druggy 420 blazeit screen looks better
The whiteness of a flash looks nicer. Mob code makes me hesitant to really change this.
The nearsighted/welding mask dither looks better

If you want screenshots just ask.

Major changes & copypasta removal in AI module code.
This won't affect gameplay.
(Untested & map won't compile, I want to have the map in a seperate commit)
Updated the default map for AI board changes.
Changes Antimov over to the new AI law system and changes it's path on the map. Various fixes to the new system.
Finalized AI module refactoring. Everything works now.
Cleaning up of AI law datums, adds Custom AI board to the map.
Honk RD design datums use string paths~
update_icons() uses animate() and transforms to actually turn the sprite rather than needing them pre-turned. Mobs that lie down do so with an animation rather than appearing on their side. You can lie down facing THE LEFT OH SHIT.

Cloakers still don't work well. The fix is probably just finding a proc that runs on equip/uequip/when bagged/when dropped. Fuck that. Ninjas work. Things that are cloaked fade to the cloaked alpha, it's pretty cool.

The "lying down" icon_states for everything you could equip are all now unnecessary. They aren't removed yet though.

The dmi changes are to make xenos all face upward so when they turn, they're lying down rather than facing south and looking like they're doing a handstand. They're not terribly good when facing the wrong way. I expect WJohnson to have a fix for this by New Year's.

Comments aren't changed. The overlays_standing list is still around because overlays is not a normal list, and BYOND's normal list functions are worth the extra cost of keeping a spare list of images.
Added a failsafe, default_laws is now a config option.
Jesus Christ it compiles
