Adds Power gloves as a new engineering traitor item! (#1797)

* Adds Power Gloves

NO GOON CODE WAS USED IN THE MAKING OF THIS PR

-Adds Power Gloves: a traitor item that takes excess power from a wire underfoot and allows you to zap people with it
-Changes the tesla_zap proc to have customizable bounces and max damage

* Removed energy_ball dependancy

-Changed tesla_zap into a specific glove_tesla_zap

-Added more checks, finalized sounds.

TODO:
fix range bug

* Final

Fixed range bug, changed a few flavortext things and made icons fit in with default actions.

* Fixes border

Changes the overlay_icon_state to be an actual overlay, fixing the error sprite.

* Improve readability

Moves if else statements slightly to improve readability

* Final2, ELECTRIC boogaloo

Uncaps burn damage with a... Mostly sane equation. Adds in dusting. May need extra balancing if too powerful.

* Requested changes

Sets code up to standards.

* Formatting fix

Literally just moved equals signs

* Power is sane

changes units to be easily readable

* Name change

* hopefully this works?

* oops

* erm?

* you silly goober

* silly goober mode

* minor refactor and logging

Refactors checks to be more efficient, logs when electrocute acts are completed.

* fixes my stupidity

seriously what the fuck was i smoking

* guh

* guh pt2

* Lights now flicker and atmos techs can buy them

:]

* sigh

* Some minor fixes and clarifications

* Fixes range bug, adds activation messages

* HOLY SHIT OOOOOOPS

* MORE fixes

* name formatting change
