WIP on refactoring the context-based combat PR
Adjusts captain announcement whistle sound

Greatly shortens the length of the whistle sound by cutting out most of
the uniform early part, and reduces volume slightly.
Update DMI state extraction
Update help text, guard against illegal values
Robotic Cable Coils
- Cyborgs and Drones can now use change-colour verb to change colour of their integrated cable coil.
Increases AI power usage

This commit increases AI power usage to 50kW. This was discussed on codershuttle and should (/w some minor lags) give the AI approximatey 60 minutes of power with fully charged SMES.
Upped Supermatter core price to 150 supply points

This is to prevent griefing using supermatter (it is bad if I can order four of them after ~20 minutes in game and destroy most of the station with them) and to be coherent with the lore - SM is SUPER FREAKING EXPENSIVE. Also (hopefully) makes the crew think before ejecting the SM 4noraisin.
Lowered SMES coil price to 75

It is a valuable piece of technology, but alone it is not really powerful at all. This is the same price as the RUST core and TE generator, which are both admittedly much more complicated. I know this was for balance reasons, but as it is now engineers will rather steal the coils from solar panel SMESes than to deal with cargo who are not very supportive of ordering expensive stuff like this.
APCs now use percent-based channel values.

- Equipment now once again shuts down when APC reaches 30%
- Lighting shuts down at 15%

This is now correctly based on APCs power cell, instead of being hardcoded. This means atmospherics and similar areas won't just suddenly go from all lit working room to darkness.
Cyborg Atmospherics Tools!

- Matter Decompiler now clears unused pipe assemblies. Long gone are the times where cyborgs couldn't remove old pipe parts.
- Engineering and Construction cyborgs now have pipe painter tool, which allows them to paint pipes properly.
AI APC now has larger power cell.
Mining robot module upgrade

- Mining cyborgs can now properly work with drills.
- Mining cyborgs have received ore scanner, crowbar, and limited version of magnetic gripper.
- Mining cyborgs can now swap power cells inside mining drills, as well as upgrade them if provided better parts.
- As a bonus, cyborgs can now see how much ore is in ore boxes (because it makes sense that cyborg which mined ton of ore can check how much ore it mined)
Merge branch 'unarmed' of https://github.com/Zuhayr/Baystation12 into unarmed

Removed antag role buffs.
Changed \red to span in unarmed_attack.dm.
Tweaks after testing.
Reverting a now unneeded var change.
