**What i've done ?**

 1. Published the package in npmjs.org https://www.npmjs.org/package/ng-token-auth also the package version.
 2. Fixed the package name in the package.json file.
 3. Added minified version in the dist dir. for better bower usage and for cdnjs.com .
 4. i'll add the package in cdnjs.com. so i had to put the lines 13 - 19 in package.json for auto-update.

Please accept ASAP in order to put it on cdnjs.com
