[core] Embedded and implement http.Pusher into http.ResponseWriter+gzip Writer (#47)

* added http Pusher interface to gzip response writer

* implement Pusher on gzipResponseWriter and pass encoding header to pusher options

* providing a generic error view fuction for code that calls a interface method which will have access to the response

* fix []byte -> string type for fmt string

* adding the res, req pattern for method arguments in interfaces and their method calls

* fix for spacing in generic error message

* remove default error views displayed in lifecycle hooks - will rely on custom views or redirects inside hook now that user has ResponseWriter. Otherwise, multiple WriteHeader calls would be warned

* removing WriteHeader calls before return in external handlers

* bump version 0.8.1
