Burning paper (and similar) is now two way (you can hold a paper to your cigarette to burn it) (#90307)

## About The Pull Request

1. Burning paper (and similar) is now two way - rather than
necessitating you touch the paper with the burning thing, you can now
touch the burning thing with the paper

2. You can now light a cigarette on a lit candle

3. Candles no longer craft into flashlight eyes

## Why It's Good For The Game

1. Burning money with a cigarette larp 

2. Cool Frenchman larp

3. ??? I noticed you can't light a candle with a candle because it tried
to craft flashlight eyes.

## Changelog

🆑 Melbert
qol: Burning paper (and similar) is now two way. Rather than needing to
click on the paper with a burning item, you can now click on a burning
item with the paper. This means you can burn paper on your lit cigarette
like a badass.
qol: You can now light cigarettes on candles. 
del: Flares and candles can no longer craft into flashlight eyes, I
guess.
