necromanceranne 4739cedebc Event Horizon Anti-Existential Beam Rifle. The ultimate conclusion to the arms race and the sniper's art. (#83934) 
## About The Pull Request

Replaces the Particle Acceleration Rifle, or the Beam Marksman Rifle,
with the Event Horizon Anti-Existential Beam Rifle.

In short, it shoots black holes.

It takes five cores to make.

It pretty much kills everything you point it at and their immediate
bystanders as well.

You can do this from the relative safety of a whole four screens away
thanks to it having a scope.

There can only ever be one vortex anomaly made in the round. The recipe,
however, always requires the maximum number of cores that can be made in
a round. If the number goes up for some reason (maybe someone wants to
add more vortex items), so does the total number of cores needed to make
an AEBR.

## Why It's Good For The Game

Firstly; the beam rifle? Awful. Jank code. Bad performance. Ancient
balancing considerations. Just too strong to bring out regularly against
specifically blobs, but completely fucking useless against anyone else.

So I'm hitting all these problems at once. I reduced a 600 line file to
less than 60. I've removed all that bad code. I've also made it
specifically unable to combat blobs at all because singularities send
blobs off to safety.

Secondly; this is maybe the first example of 'more cores = bigger
power'. The rifle was already utterly trash to have around, and I just
didn't think the way it worked currently could really excite anyone
enough to go on a big ol' quest to get it. Solution?

You will cause a shuttle call if you get this weapon.

## Changelog
🆑
add: Replaces the Particle Acceleration Rifle with the Event Horizon
anti-existential beam rifle. It shoots black holes. You can make this
in-game. That's right, YOU!
balance: Only one vortex anomaly can be made in a round.
