Misc night mode CSS
Merge pull request #406 from geekman3232/master

Changed superscript button's behavior on comment tools module.
Merge pull request #405 from xraystyle/master

Typography update for deviantART links.
Fix for HoverZoom/Character counter/BigEditor

Hover Zoom removes the title attribute on hover which was causing the
page to move up and down when hovering image links. Since the character
counter relied on that attribute for its CSS, it caused it to break
position and make the page move up/down by x amount as it lost/regained
its styling.

Big editor button styling was broken on wiki pages due to a bum selector
by yours truly.

Fix for HoverZoom/Character counter/BigEditor
Firefox fix for collapsed image expandos

Long-standing issue with Firefox whereby image expandos in comments that
have been opened and then collapsed are broken. This is due to Firefox
prioritising CSS from reddit over RES (reason unknown).
