Valid xhtml and org-html.el

Hi,


appended is a patch for org-html.el.


This is what it does:

  1. <col></col> is no valid XHTML. Coltags must be empty. I.e., <col .... />

  2. <colgroup>...</colgroup> tags where missing

  3. A minor fix for the end of the CSS comments. Safari doesn't like
     /*]]>*///-->
     and is right in this case. `//' does not start a comment in CSS.
     Therefore, I changed it to
     /*]]>*/-->
     which is valid and Safari shuts up.

  4. Change `&' in link descriptions to `&amp;' again.
     Not sure if I did it in the right place though, but I guess
     `org-export-html-format-desc' is only called to format link
     descriptions.


Apropos validation:

  I worked a little on org-search.php this weekend. It now works without
  networking by default and is much faster.
  
  Also, you may now use it without a database, just to validate the
  XHTML output. No installation required anymore. In that case, the
  script just scanns the first 10 files (customizable) found and
  displays the parser-errors.
  
  If you use the script with database, wrong links to images are
  detected now. That's nice, when moving files around in your
  org-directories.
