[Experimental] New component layout

I'm experiment with a simpler standard component layout. The goal behind this is lower the barrier to entry when working on, or building new, components.

The major changes are:
- removal of the `.jshintrc` which rightly belongs in [asimov-build](https://github.com/asimov/asimov-build).
- removal of `/src` directory in favour of the root directory

The sass compilation works without any changes to existing build systems (@import paths will however need to be updated).

The js compilation requires an update to asimov-build, but shouldn't affect upstream consumers.
