3 days late /o\

we're 3 days older than https://github.com/sindresorhus/globby, but too
slow on the npm side of things :-/

might change this to a thin api on top of the other globby, if it performs
well enough in the cases we care about (e.g. glob *.js in giant project,
exclude node_modules, etc.)
readme tweak, version bump
