Travis build failures due to grunt plugin peerDependency problems

[sirbarrence]

The old semver of grunt-ng-annotate referenced in the package.json file along with the * semvers on all the other grunt plugins is causing Travis builds to fail on npm install with output like

npm ERR! argv "/usr/local/bin/node" "/usr/local/bin/npm" "install"
npm ERR! node v4.2.1
npm ERR! npm  v2.14.7
npm ERR! code EPEERINVALID

npm ERR! peerinvalid The package grunt@1.0.1 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer grunt-contrib-concat@1.0.1 wants grunt@>=0.4.0
npm ERR! peerinvalid Peer grunt-ng-annotate@0.10.0 wants grunt@~0.4.5
npm ERR! peerinvalid Peer load-grunt-tasks@3.5.0 wants grunt@>=0.4.0
npm ERR! peerinvalid Peer grunt-contrib-jshint@1.0.0 wants grunt@>=0.4.0

For instance this build.
