Update HTML in  "include" files

Udated the DOCTYPE to make it W3C standard/compliant.

Moved "sorttable.js", "ticker.js" and the "antiClickJack style" from
"fbegin.inc" and place them in "head.inc" (where they belong), this may
also help the Widescreen package to work.

Close BR, INPUT and IMG tags properly, update IMG tags with "alt" and
update TABLE tags with "summary".

Updated the SCRIPT and STYLE with proper CDATA sections.

Updated LINK with the correct types.
