3.5.57

Implemented Cache tags for Cloudflare Plans. This is an optional implementation, the default way of working is to still purge by URL, but this allows for cache tags to be used on any cloudflare plan when hosted at Servebolt. This reduces cache purge time significantly.

Also implemented a bugfix for Chrome browsers so it clears the cache quicker when logging in. Now is an instant login rather than taking time. And added corrected cache clear method for firefox browsers which require a GET request not a POST request.
