Batrachophreno 0c342878e5 Engineering spriting (detailing & port), portable shield balance, bugfixes (#21862)
EXTREMELY MINOR MISCELLANEOUS CHANGES TEEHEE

changes:
- imageadd: "Adds +bolted, +welded, +lights overlays to several large
machines for easier visual identification of whether or not clicking on
that emitter will kill you or not, etc."
- imageadd: "Modifies the base of the Shield Wall Generator sprite to
better match that of the Emergency Shield Projector (and so they can use
the same overlays mentioned above)."
- imageadd: "Tweaks the Emitter's directional sprites slightly so that
the base doesn't seem to change shape quite so drastically when
rotated."
- imageadd: "Ports very pretty space heater sprites made by Wallemations
and vinylspiders from /tg/."
  - imageadd: "Adds unique sprites for Old and Heavy-Duty power cells."
- balance: "Increases power draw and range of Emergency Shield
Projectors."
  - balance: "Increases power draw of Shield Wall Generators."
- balance: "Greatly reduces time for debugger to fix APCs corrupted by
electrical storms."
- balance: "Increases multi-z shield capacitor reserve charge and
maximum throughput, so that high-strength shields can actually be run
(at high power draw)."
- balance: "Tweaks the INDRA power output formula to scale better with
increasing temperature."
- balance: "Slight adjustments to space heater efficiency formula with a
friendly handwave to entropy."
- balance: "Old power cells have a 5% chance to be defective and have
slightly lower maxcharge than standard cells."
  - qol: "Adds extended examine hints to engineering objects."
- qol: "Extends list of object types which INDRA core field will
interact peacefully with."
- qol: "Improved space heater UX (chat msgs changed to balloon alerts,
audible feedback, etc.)"
  - code_imp: "Updates many code comments to use DMdocs."
- code_imp: "Consolidates various shield generation machine sprites in
scattered across multiple files into a single shield generator machines
sprite file."
  - bugfix: "Fixes Emergency Shield Projector hard del issue."
- bugfix: "Emergency Shield Projector now shuts down as intended if the
area's APC gets completely drained."
- bugfix: "Firing the gyrotron into the INDRA while no reactants are
present will no longer generate heat."
  - bugfix: "Fixes INDRA runtime."
- bugfix: "Fixes Power Monitoring app not displaying grid sensors when
run from a modular computer held in-hand."

Modified shieldwall sprites (with old ones for comparison)

Shields actually useful for damage control now (though they'll blow
through APC charge if you go as crazy as this):
