Use Arrow Keys to move Crew in Engineering

[parracodea]

Avoids duplicate keybinding in Engineering+, where S moves the Crew down, but also toggles Shields

---

For Weapons station, S toggles shields and in Engineering, W A S D moves a Crew Member. However in Engineering+, they have the ability to do both, so moving a Crew member also causes the shields to be turned on/off.

The default keybinds have been reassigned as follows:

Action	Original Key	New Key	Additional Note
"ENGINEERING_POWER_100"	Space	\\	Backslash to reset power levels since it's next to the increase/decrease keys ([, ])
"ENGINEERING_POWER_INCREASE"	Up	]
"ENGINEERING_POWER_DECREASE"	Down	[
"ENGINEERING_COOLANT_INCREASE"	Left	=	= since its the same key as +
"ENGINEERING_COOLANT_DECREASE"	Right	-	See note below
"ENGINEERING_REPAIR_CREW_NEXT"	Q	C	C for "Crew" to follow the convention where the letter matches the action name
"ENGINEERING_REPAIR_CREW_UP"	W	Up
"ENGINEERING_REPAIR_CREW_DOWN"	S	Down
"ENGINEERING_REPAIR_CREW_LEFT"	A	Left
"ENGINEERING_REPAIR_CREW_RIGHT"	D	Right

Note: There's a bug in SeriousProton where it's unable to read - as a keybind from keybindings.json. See daid/SeriousProton#243 for a fix (which should probably be merged before this PR).

Thanks for all of these! It's the little things that are a lot of work and easy to miss.
