Never miss a verion number again!

Updated grunt to use the version inside the package.json file and populate all of the built source files.

new package added: grunt-string-replace

There was also one small syntax issue in docs.scss that was causing the        build to fail. Fixed that.
Revert package.json

reverted some of the non-required changes made to package.json to see if it will fix the build.
Merge pull request #5579 from joeworkman/string-replace-version
