Spoike d561772bb0 stripped support for qvm-based plugins. rewrote native plugins to use a more efficient interface.
merged engine menus, native menus, game menus, plugin menus into a single layered menu interface, simplifying all the special-case input.
engine confirmation prompts can now show regardless of underlaying menus, including above the console.
skeletal formats can now provide their own way to build bones, for variable per-bone keyframes/interpolation methods/etc (used by gltf2).
updated various plugins for the new api.
removed qvm makefiles/scripts.
