Document the changes in your pull request

ports over a few optimized systems for less delay and faster systems
depreciates HEAR 1 flag and is replaced with important_recursive_content()

Why is this good for the game?

this ive been throwing on and off the back burner has gone on for long enough.
getting this out of the way means we can have almost little to no slow down with large amounts of radio chatter as well as adding and removing things in the game when a client is or isnt using that band anymore

Testing

Remember: something that is self-evident to you might not be to others. Explain your rationale fully, even if you feel it goes without saying.

Actually explaining what this does in greater detail is a huge help to both maintainers and anyone else reading your PR. At least try to list what you've changed.

The important recursive contents stuff also does the same but for something else I got to check once I get home
