docs(CONTRIBUTING.md): fixing link to Google Closure I18N library

The old seems to link to the source code of I18N. Found the same folder on their new Github repo.

"Closure Library's source repository has moved to GitHub.", https://code.google.com/p/closure-library/

Closes #7638
docs(ngKeyup): improve example

show implicit `$event` argument
docs(tutorial/step_05): improve explanation of _-prefix
docs(tutorial): add instructions to make experiment render readably in step 5

Update step_05.ngdoc

Closes #7653
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
to do. So I say, LGTM!

Closes #7602
docs(*): fix its/it's grammar

Closes #7580
chore(ngLocale): change update-closure script to pull from github, not code.google.com

The closure-library migrated a while ago, so the script would fail. This is change
should allow us to update these more frequently.

Closes #7668
fix(ngLocale): fix i18n code-generation to support get_vf_, decimals_, and get_wt_

The updated Closure I18N code relies on these methods to enhance the localization quality.

This fix prevents ngLocale files from referencing undefined values. In the short term, this
means adding references to versions of these methods in locales where they are necessary.
chore(ngLocale): update ngLocale scripts

This is a batch of updated ngLocale scripts, based on the recent fixes.
fix($parse): fix parsing error with leading space and one time bind

Closes #7640
fix(ngAnimate): $animate methods should accept native dom elements
refactor(bootstrap): remove an unused argument

The $animate service is injected, but not used within the code anymore.

Closes #7649
docs(guide/providers): fix grammar
docs(guide/providers): fix typo
docs(tutorial/index): fix typo
docs(guide/expression): fix docs re $window

The documentation on context is incorrect and misleading:

1. "Angular expressions must use $window explicitly to refer to the global
   `window` object": expressions cannot access `$window`
1. The example doesn't actually attempt to use $window in a expression. It's in a
   function called from an expression, which incorrectly implies to readers that:
  1. functions ARE expressions
  1. functions called by expressions can't access `window`

Here's [a plunkr](http://plnkr.co/edit/Gd4xAV?p=preview) to make both these issues clear.

This change fixes the errors and informs the reader about Angular's `$window` etc services,
and adds an explicit example of an expression not being able to access `window`.
docs(index/api): fix link o templates

Link points to templates. Modified the link label templates instead of types.
docs(misc/faq): note that jQuery 2.x currently doesn't work with angular
