chore: run docs unit test only once

Before we would run them twice on Travis. I don't think it should be part of ci-check task.
fix(jqLite): support unbind self within handler

If an event handler unbinds itself, the next event handler on the same
event and element doesn't get executed.

This works fine in jQuery, and since jqLite doesn't support .one, this
might be a common use case.
docs(ngIf): remove invalid comment from CSS

We cannot use valid /* ... */ CSS comments in examples because they break the parsing
of the ngdoc comments.  We can't use inline // comments because these are not valid in
CSS.

We could use the //!annotate extension to the ngdoc parser but this does not seem to be
working.  It is best to simply remove this line.

docs(): fix jshint issues
docs(tutorial/step-11): change "last" to "next"

Since step 12 was added, step 11 is not the last. So this is not the last improvement.

fix(select): invalidate when 'multiple`, `required` and model is `[]`

When `multiple` attribute is set on a `<select>` control and the model value is an empty array,
we should invalidate the control.  Previously, this directive was using incorrect logic for
determining if the model was empty.

perf: use faster check for $$ prefix

Use two calls to charAt instead of substr to detect a $$prefix in the shallowCopy functions.
This makes shallowCopy 25-50% faster (depending on which browser is used).

docs(bootstrap-prettify): fix $timeout issues and update related docs

End 2 end tests wait for all `$timeout`s to be run before completing the test.
This was problematic where we were using timeouts that restarted themselves because
there would never be a point when all timeouts had completed, causing the tests to hang.

To fix this $timeout had been monkey-patched but this caused other issue itself.

Now that we have $interval we don't need to use $timeout handlers that re-trigger the $timeout
so we can ditch the monkey-patch.

This commit tidies up any examples that are using this approach and changes them to use $interval
instead.
