Add support for KVM/QEMU as a backend to use non-x86 hosts

[TMinusBlastedRocket]

I am a nut who runs openpower (ppc64le) in my lab, it would be cool if i could use it for vms in minecraft, bonus points if serial consoles are a vaild display and if non host architectures are supported (i.e emulating SPARC64 on an AMD64 host via QEMU) QEMU should give decent APIs for using it, so i think it's worth considering

Note: if using qemu, please make sure that the configuration txt file for the vm is editable directly in the game

See #53

And yes we will allow this. Most likely gonna be a JSON config per VM.

Also do you guys have plans for captured input, I plan to do gpu passtrough and have a gaming pc in minecraft on my other (non-ppc) server

Doesn't seem like a hard feature to add, so potentially.
