Unmaintained Adsense Placement for XenForo Forums - One Way to Do It

I fixed a typo where it said "320x250" instead of "300x250" in some of the templates (thanks, @dvsDave ).

Also moved some of the code from the footer template (no longer used) to the ad_below_bottom_breadcrumb template.

Added exclusions for non-content pages in order to comply with Adsense policies.
