Power-lines snapping animations, power-line-spark particles, and meteor-explosion particles!

tl;dr: Last week was a short week for me, but I did add some new animations and particle effects for power-lines snapping and meteors exploding.

What happened last week?

Highlights

It was a short 3-day week for me.
I did a lot of blue-screen-of-death debugging.
I added new animations and particle effects for power-lines snapping and meteors exploding.

Add a snapping animation when power-lines are destroyed.
Add support for configuring whether each end of a snapped power-line should drift or be fixed in-place.
Add particle effects for power-line sparks and meteor explosions.
Fix particle scales and start frames.

Disable build-station commands when there is already a command queued for building a station at that site.
Hook-up the barrier-bot character.
Increase trajectory expected-frame-count-deviation tolerance.
Update level-end condition to be when the command-center runs out of health, and deactivate the command-center shield when running out of energy.
Fix a rare bug where wall-grab and wall-touch directions could be inconsistent.
Update constructor-bots to be built from the command-center without needing another bot to be present to build them.
Add support for configuring specific types of bots to only be able to handle certain types of commands.
Update power-line collision geometry to use multiple sub-segments, which more accurately represent the wire's curve, rather than a single straight segment from start to end.
Update runtime edge-trajectory validation to not fail when a collision is detected one frame later at runtime.

I spent most of my time trying to debug the cause of the non-deterministic blue-screen-of-death crash on my PC.
:( Sadly, I still haven't found the culprit!
It seems like it must be due to a faulty piece of hardware.
I factory-reset Windows, and the issue still occurs, so it doesn't seem to be software-related.

🎉 Cheers!
