Remove reference to non-existent view

Analytics view is not provided in core. This results in a PHP notice
issued everytime a page displays the foot view.
Revert "Remove reference to non-existent view"

This reverts commit 64acaadfa2f490794e513aeef35f8710aae7db49.
Deprecate analytics view

This is a reference to a view that is not part of the core. It should
be handled similiar to the way metatags view is handled in head.php.
Otherwise, a PHP notice is generated everytime the view is requested.
Update notice
Update CacheHandler.php

This line looks suspicious. Shouldn't the `$request_var` start with a `/` ?
If I have `/cache/0/default/css/admin`, I'd rather have
  `$request_var = "/0/default/css/admin";`
than 
  `$request_var = "0/default/css/admin";`

I don't know how it works with Apache and others, but with Nginx, it simplifies things. Therefore:

  `if (!preg_match('#^/?([0-9]+)/([^/]+)/(.+)$#', $request_var, $matches)) {`

(drop the `?` if that is not needed)
