Add is_upgrade() free function: fix #195 This function returns `true` when the passed HTTP Request indicates a WebSocket Upgrade. It does not validate the contents of the fields: it just trivially accepts requests which can only be a WebSocket Upgrade message. Callers who wish to manually read HTTP requests in their server implementation can use this function to determine if the request should be routed to an instance of websocket::stream.

Refactor method and verb (API Change): The verb interfaces now use verb::unknown instead of boost::optional<verb> == boost::none to indicate that the request-method is an unrecognized string. The http::header interface is modified to focus more on the verb enum rather than the string. For recognized verbs, the implementation stores an integer instead of the string. Unknown verbs are still stored as strings. * header::method now returns a verb * header::method_string returns the method text
