Consider flattening structure to support other module types later (components, systems, primitives)

[ngokevin]

We could perhaps cross this road later once we consider support, but good to get feedback. This is easier than managing different aspects of a package across different keys.

Current:

components:
  aframe-physics:
    names: body, joint

to:

aframe-physics:
  components: body, joint
  systems: physics
  primitives: a-newtons-cradle

[feiss]

yup, this has lot of sense. And if is only a component, no problemo:

my-cool-component:
     components: my-cool-component
