docs(tutorial): add karma config update reference to step 11

When including the ng-resource module you appear to need to add a reference to the karma config file
as well or the unit tests will fail. This burned me for a while when going through the tutorial.

Closes #7651
docs(tutorial): fix minor errors in step 11

I added these when amending the previous commit. My bad ._.
docs(orderBy): add example of directly calling $filter('orderBy')

It's not a bad example of sorting fields in a table, which is something people are frequently wanting

should allow us to update these more frequently.

fix(ngLocale): fix i18n code-generation to support get_vf_, decimals_, and get_wt_

means adding references to versions of these methods in locales where they are necessary.

This is a batch of updated ngLocale scripts, based on the recent fixes.
