Adds a large ash and large molten item decal (for future use)
simplifies decal/cleanable/replace_decal() code a bit.
Changes construction() proc to on_construction() for consistency, same for deconstruction().
Made a deconstruct() proc for machinery and computer (also for future use).
Added priority overlays to atoms, which will not be removed when overlays are cut and will always remain on top when new overlays are added. This requires everyone to use add_overlay() and cut_overlays() instead of overlays += and overlays.Cut(). These procs are found in __HELPERS/icons.dm, and the priority overlay list is found in game/atoms.dm. Everything else is replacing deprecated overlay manipulation.
This PR finishes work started in #17300 by making all the machines use apply_default_parts(src) for components initialization.
It also adds two new board sprites, one for Abductor boards and one for Ravtar boards:
board board_a board_r
There are no deconstructable Ravtar machines yet, sprites are added for future use. Abductor sprite is used only by Seed Vault's plant DNA modifier. It wasn't made by actual abductors, but it was surely made by aliens.
Boards now have a new var: def_components. It is a list containing replacement paths for default parts. For example, list(/obj/item/weapon/stock_parts/matter_bin = /obj/item/weapon/stock_parts/matter_bin/super) would make machine spawn with super matter bins instead of basic ones by default.
Console screens that were used in machines instead of glass sheets are replaced with actual glass sheets. Support for sheets as machine components was added in a previous PR
These are the files with just tiny tweaks. Mostly modify an object's attackby so it does "return ..()" instead of "..()".
If there are other things in this commit, the PR's description will explain them.
Fixes SMES deconstruction logging.
Radiation will no longer message admins unless a living mob is hit.
All rad pulses will still be saved to logs.
Also adds a JMP link to the rad pulse message.
Fixes#12442Fixes#12609
obj/effect/effect is now renamed obj/effect/particle_effect for better usability.
datum/effect/system and /datum/effect/effect/system are now both /datum/effect_system.
Fixes a bug where wall mounted igniters (and other spark producing objects) didn't produce sparks sometimes.
Moved explosion_particles.dm into the effect_system folder, because it has effect_systems code.
