Work on experimental support for the Forge modloader.

Forge support has hit a momentary stop, as I have to figure out a way to include the minecraft-common library with Architectury-loom. There's a lot to learn about gradle and packaging before I can make that work.

Can we just wait for 1.21 and use connector as its actually setting up to be a really stable api?

Yeah I agree, it's probably better to rely on Syntra for the time being.
