Add HTTP_HEAD to HTTPMethod and parse it (#6413)

* Add HTTP_HEAD to HTTPMethod

* Parse the HTTP_HEAD variant of HTTPMethod from a method string

* Add HTTP_HEAD to the ESP8266WebServer constants

* Skip sending the content of the response if the HTTP method is HEAD method

* Convert the HTTP status code 418  to string
This status code is an easter egg from the IETF and is described in 
[RFC2324](https://tools.ietf.org/html/rfc2324#section-2.3.2)
