Please publish v1.9.3 on npm

You have v1.9.3 in changelog. However, there is no v1.9.3 on NPM: https://www.npmjs.com/package/growl

Publishing v1.9.3 on NPM is important because of security issue: https://www.npmjs.com/advisories/146/versions

Publishing v1.9.3 on NPM will solve some security issues, probably #66.
However, there is need to write to NPM about that fix, see #67.
