1.19.2-v1.13.12-4

This release adds even more madness.

• A new encoding called "Invis2" as proposed by JamSharp. Basically binary, but looks like chat spam.
• JamSharp also proposed a new compression standard. Which is why this adds 2 new compressions: Brotli and Custom (dictionary based)
• Compression policy and a fixed compression can be chosen in the encryption config menu with new buttons and tooltips describing them

The compression uses a different prefix to prevent users from seeing binary gibberish. If you for some reason can not decrypt messages from people you know that you have the key of, they probably use compression. By default it should be only used in circumstances where the message would be cut anyway.

There some smaller fixes:

• CTRL+Enter now actually works as the tooltip suggests (sends message without encryption)
• The "Used key" button now actually shows the tooltip which was intended to tell people how multiple keys work
• Probably some other stuff I forgot to mention

I'll mark this as a pre-release for now. I might turn this into a release or release a never version, depending on whether this still contains bugs or not.

Edit: This release is already bugged. Brotli doesn't work at all in this one. Will be fixed in then next release in probably 1 day.
