Real plugins added to Showtime
Starting from 3.1.126 Showtime now support "real" plugins.
By "real" plugins I mean plugins that can be loaded and installed from an online repository.
This allows third party plugin developers to rapidly develop plugins and make them available to the general public.
It's also possible to copy a plugin (which is just a .zip-file) onto a filesystem that Showtime can access and then just install the plugin from Showtime itself.
I've also started to write some documentation for how to develop plugins.
