Remove external link tracking

This isn't used anywhere and isn't an approach we should use.
Remove hash navigation fix

This isn't used anywhere. It also has logic in it to ensure the sticky
heading bar doesn't cover the content. The header bar isn't sticky and
hasn't been for ages.
Remove popup javascript and styles

Fairly sure these aren't used any more.
Remove unused button hover and focus JavaScript

This JavaScript was adding classes that were never used anywhere. The
only place that they were used, the header, no longer has an input with
the `.button` class. Removed the CSS from the header which wouldn't have
targeted anything.
Mark the beta_label template as a non-layout template

Include "beta_label" as part of the NON_LAYOUT_TEMPLATES list, so that 
we don't show the GOV.UK wrapper around it when we include it in 
other pages.

Add YouTube account verification file

We need to validate our YouTube account so we can embed deep links in
the annotations.

The primary use case for this is linking out to help or transaction
start pages from instructional videos hosted on YouTube, e.g link to the
passport application process from a video about the transaction.

Bump toolkit for footer updates
Update footer CSS to be the same width as header

The footer was wider than the header on anything below 1024 width. This
changes the markup so it now matches the header grid and resizes at the
same points as the header and the copyright notice below it.

Moved to two floated elements of 1/3rd and 2/3rd widths respectivly
rather than elements close to those widths.

Updated code to use the `media` mixin rather than the `media-down` which
meant we were able to reduce a large amount of code.

Added a `<hr>` for the break between the links and the copyright as
couldn't use a border on any elements as they were `15px` to wide on
either side due to them containing floated elements which managed their
own gutter.
