Example should show how to use ui-sref-active instead of ng-class
chore(README): don't try so hard to scare people
chore(config): 'dist-pages' task.

Set up two different grunt tasks—'dist' for a clean build and 'dist-pages' for a clean build plus ngdocs. Then 'publish-pages' task uses 'dist-pages' so the docs only appear on the gh-pages branch, keeping master more lightweight.
Merge branch 'master' into ngdoc-improvements
chore(ngdoc): More ngdoc improvements
