Remove the inuit.css submodule (SASS version)
Add the LESS port of inuit.css as a submodule
LESSify the _vars.scss
LESSify the _style.scss

It's necessary to import the defaults here because there is no such a thing as `!default` in LESS
Otherwise, the core framework import would have override our custom variables (imported in second position)
Remove watch.sh
Update README to add LESS port information
