Subject: Added "if(!function_exists('xpost_to_html2bbcode'))" This function
 name is also used by post to friendica plugin Both functions seem to be
 identical. If you have both plugins installed you get an error because of the
 identical function name This will avoid the attempt to load the function a
 second time in case it was already loaded by the post to friendica plugin
