Fixes #410 - Retrieve title fails in multiple cases * `get_http_url()` renamed to `get_http_response()`. * Use the same HTTP context to retrieve response headers and content. * Follow HTTP 301 and 302 redirections to retrieve the title (default max 3 redirections). * Add `LinkUtils` to extract titles and charset. * Try to retrieve charset from HTTP headers first (new), then HTML content. * Use mb_string to re-encode title if necessary.
