Fix some issues with comment submission

- Fix error when submitting comments being ignored, meaning you'd only know if your comment got rejected if your comment wasn't there after the comments refreshed
- Fix issue in Request::ParseResponse where "Could not read response" is always included on all website errors
- Add ability to refresh comments by clicking the Submit button with an empty textbox
