RustFriends 13.1.3

Good Question Flint Monkey.

I asked for the fix I came up with to be integrated years ago, to avoid bot to be added and it was rejected as it was a "Rust centric" fix and some other games might use those id...  They said to get all the plugins using friends to filter...

I forked it out of frustration, and as a pragmatic solution.  This was back when it was open source.  I can't touch the current code due to the license change, but work to keep my code API compatible.

I could split out the friend file cleaner code, and make a stand-alone cleaner, it is a tiny bit of code, but better to avoid it all together.

If they would block bots, I would take mine down in a heartbeat.
