Converts del logging to proper json, using json objects instead of building a text file (#75636)

## About The Pull Request

It's easier to parse, and makes more sense when you read it. This way
I'll never have to add yet another case to my parser for someone
changing where a space goes or something.

Moves qdel into its own category cause the old name looked ugly (yell if
this is dumb)
Added a bitfield to entries pulled from categories, adds a new flag that
enables pretty printing json lists.


## Why It's Good For The Game

IMPROVES my workflow

## Changelog
🆑
server: del logging is now done by outputting to a json file again, but
this time we're using ACTUAL json and not just a big text string with
newlines and shit
/🆑
