Remove obligation to put something between plugin and php on plugins filename
I remember that we used that a long time ago to check if the plugin
was enabled or disabled, but now with the plugins.states.json file
I don't think we need it anymore. I would love to remove the last
catch all (*) but it's better to keep it to be able to load old
plugins.
