Allow ftlabs npm account to publish new versions of ftellipsis on npm

I guess this is testament to the stability of this code, but over a year after the last release of this module it'd be kinda nice to release a new version that gives more useful error messages... @wilsonpage could you add us to the approved maintainers?

npm owner add ftlabs ftellipsis
