even better "parent" button selector

fixes regression from dee61fc28ba6d3e6c82c41dbd5c719ade5c0ac8a. probably slightly more efficient, too.

assumes that "permalink" button will always be first button, which is a terrible assumption but it's still better than the previous version
showParent.show checks for parent comment existence before setting up hover div

Look before you leap, because I disapprove of try-catch in JavaScript; and it's slightly more efficient this way
Fix issue with not connecting to the immediate child of an expanded
set of comments. In particular loading top level comments was not
firing newCommentForms

Subreddit styles CSS

Close another couple of loopholes. Max-height/width could be set to `0`
and override height/width, effectively hiding the checkbox/label.
Setting them both to `none` negates that.
