Relates to #333 Modifications: - move HTTP utils to 'application/HttpUtils.php' - simplify logic - replace 'http_parse_headers_shaarli' by built-in 'get_headers()' - remove superfluous '$status' parameter (provided by the HTTP headers) - apply coding conventions - add test coverage (unitary only) Signed-off-by: VirtualTam <virtualtam@flibidi.net>
