[OzzModz] XFRM File Extension And Size Display 2.0.1

Support: XF 2.2

Added file hash info. Hash is truncated to fit the display, but hovering over it opens a tooltip showing the full hash.

• Cleaned up template modification to get a savings of approx 0.0008s on page view.
• Changed addon icon displayed in the ACP from a png icon to a font awesome icon.

Thanks to @kick for reporting the issue.
