General improvement over responsive theme.
- Removed leftovers of SuperFish
- Removed some testing code for responsive menu handling (button also)
- Avoid <br> on some point to make it look better on mobile
- Removed HTML5 Breadcrumbs (Works well only under SEF URL)
- Changed Moderator box style bit more (small font-size/bold font)
- Toggle button (SCEditor) bg-changes.
