SmArtKarandGitHub dbadf01a35 Readds sovlful IEDs and adds assembly beakerbombs (#94965) 
## About The Pull Request

This PR sort-of brings back old IEDs, albeit much more freeform compared
to their previous iteration. Using #94861's ``spark_act`` interactions
they can now be made by filling up a soda can with a variety of
chemicals (welding fuel being the easiest to obtain), dunking in a piece
of wire, taping it up (optional, required if using welding fuel or
plasma) and lighting it on fire with a lighter or welding tool (anything
that's hot enough works, really)
They have a random delay of 2-4 seconds, and can be disarmed by snipping
the fuse with wirecutters in time before they detonate (or don't,
depending on the mixture)

There's also a new, more "professional" improvised chemical explosive in
the form of beakerbombs. These can be assembled by putting a lid on a
beaker (alt-click, prevents the beaker from spilling its contents when
thrown) and attaching an assembly with an igniter or a condenser to it.

/>

When triggered, igniters will heat the reagents up by a bit while
condensers will cool them down. However, you can also attach and wire up
a power cell, which will cause it to dump all of its power into the
beaker when the igniter fires off, triggering ``spark_act`` interactions
potentially causing a larger explosion.

Decently sized boom from The Contraption.

Plasma and welding fuel's potency inside of beakerbombs/soda cans is
significantly reduced compared to other riggable objects (strengthdiv is
3 times higher) as they're very easy to obtain and would make for very
powerful explosives, considering their very strong strengthdiv as most
rigging interactions use very little fuel/plasma to cause a large
explosion, which was carried over to the new system. (Don't worry, this
still leaves them at sensible values with welding fuel being about as
strong as old IEDs on average)

Closes #94990 via having plasma's electrical power modifier have a
decline past a certain point based on its volume

## Why It's Good For The Game

#81529 didn't justify IED removal whatsoever and I think with new
mechanics these can be used as easier (but weaker) to make improvised
bombs, being much less clunky to make and use than pipebombs.
Beakerbombs are essentially a somewhat weaker (even with metamat
beakers, you're still 20u short of a normal large beaker grenade at
200u) form of grenades, but have access to new interactions involving
charged up explosions, which could make for some variety among chemists'
weaponry.

## Changelog
🆑
add: Added back IEDs made by attaching some wire and tape to a soda can
filled with fuel, plasma, or any other explosive of your choice. They
need to be lit on fire with a lighter or a welding tool.
add: You can now attach a lid to beakers with alt-click, preventing them
from being spilled when thrown.
add: Added beakerbombs, made by attaching an assembly (with optional
power cell and wiring) to a lidded beaker.
balance: Rigged explosions now create flames.
balance: Plasma explosions now limit their explosion potency past a
certain point based on their volume
