V4 (#55)

- The composition json is now _just_ the AST with no implicit lowering.
- `composer.lower(composition, [combinators])` is now exposed and gives control over the lowering (if desired).
- The `compose` command has two new options: `--lower` and `--version`. 
- The combinators are now automatically derived from spec, e.g, `if: { args: [{ _: 'test' }, { _: 'consequent' }, { _: 'alternate', optional: true }], since: '0.4.0' }`.
- The spec for the combinators is now exposed as well (`composer.combinators`).
- The core language has shrunk thanks to `composer.mask` and a more aggressive use of lowering.
- The fsm has fewer states.
- The code is now split into three components: 1 compiler component available client-side and server-side, 2 client-side composer, and 3 server-side conductor.
