Updates to DokuWiki authhttp and authsplit plugins

I’ve just pushed Bugfix updates for my two DokuWiki plugins:

• authhttp has received a small, but important bugfix: its config interventions, eg. disabling the “login” action, used to apply already as soon as the plugin was activated, even if it wasn’t the active authentication plugin. This caused weird effects when trying out other auth plugins.
• authsplit has also received a bugfix: in createUser() we always tried to create the user in the primary auth plugin as long as it supported creating users, even if the user already existed. This didn’t show up with authhttp, of course, as it can’t create users, but caused trouble with authmysql, for instance.
