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
