[PR] EMAG disables borg interface locks instead of freeing them

[xenomni]

I think it should open the chest component (`src.opened`) instead of the head case for the following reasons:
* Prevents two-click, no tool round removal (emag -> swap hands -> grab brain)
* Emagger can remove the power cell to prevent radio callouts/immediate reprisals (borgs with no cell can still move, but can't use radio/tools)
* Emagger can immediately use a cyborg law linker to link them to a new rack (yay synergy)

I think this is a much more interesting solution. My biggest issue with this now is that removing a cyborgs brain gives 0 alert to anyone and its on the antagonist to say they've done this. Which in most cases why would they? I think having it open the chest is interesting, the law linker bit is actually super cool esp for a traitor CE for example, the ability to subvert cyborgs without being a roboticist or MDir and without directly touching the regular lawrack is an interesting play idea. It would take some talent to pull it off I dont think itd be particularly easy and that's interesting.

EDIT: Also potential to force an erebite or artifact cell on a borg with this
