add button to clear individual notifications from inbox
i tried to look into the changes you suggested... i haven't had enough time to really Grok how symfony works to be able to refactor the controller/model layer as well as i had hoped. but, i did remove the bad HTML, and changed the button text to "Clear notification" which is hopefully better for a11y, although it does push the text in the comment display over a bit (but not enough to look bad, at least on my screen resolution). i saw hollyhoppet is working on upgrading so i figured i'd go ahead and file the merge request in order to get this on the new jstpst, but if it's not up to quality standards i understand.
thank you for your time!
