Enhancement: Support more platforms out of the box

[GlaireDaggers]

Right now binaries and project configs for 32 and 64 bit Windows builds are already provided, but anything else (Linux, Mac, etc) requires some extra legwork from end users not only having to compile FNA3D, SoLoud, and get SDL2 binaries, but also having to configure the project too. Would be nice if I can find a way to get these other binaries compiled and provided along with the right project configs.

I don't currently have access to a Linux machine, though I've been thinking of snagging a LattePanda as a home build server so that might be a good candidate for making Linux builds. Mac, I think I'll need some outside help with making builds. Don't exactly have the funds for a Mac right now.

Other platforms should be investigated too (Android & iOS), but I don't think Beef directly supports them from the IDE yet so likely a low priority.
