  In HTML2BBCode: fetch the URL of [EMBED] using JavaScript instead of an ajax-call to a php-script. Once there actually is embedded Code in the HTML, this function is called after every single keypress. Not only is making an ajax-call every keypress bandith intensive - it also made typing hard / slow. Making a lot of JavaScript-RegExp-Computation every keypress isn't exactly great either, but still performs better.
  Some security against XSRF-attacks
  A 'PHP Fatal error:  Call to a member function getElementsByTagName() on a non-object in mod/parse_url.php on line 191' occurred when the linked HTML-File doesn't have a HEAD. The HTML-file couln't be link to in the editor therefore.
  Mostly some checks in order to avoid Notices; 1 real bugfix in /mod/network.php
  Avoid notices
  contact.network is used later to check if a direct link or a redirect by /redir/contactid should be used
  wasn't actually changed before
  Avoid a notice
  Avoid a Notice
