Plugin no longer works with known master

[zoglesby]

Fatal Error: /path/to/known/IdnoPlugins/S3/Main.php:21 - "Uncaught Error: Class 'Symfony\Component\ClassLoader\UniversalClassLoader' not found in /var/www/known/known/IdnoPlugins/S3/Main.php:21

It seems that this is because the change to composer, I tried adding class-loader to my composer.json and then requiring UniversalClassLoader in the Main.php of this plugin, but it appears to be missing in the most recent version.

I am going to poke around at this more later, but wanted to capture the issue for now.

The S3 plugin is going to need a little love in order to work with modern core, but it shouldn't need major changes.

You don't need the universal class loader. Either specify the s3 library in a composer json, or use SPL to load it.

You'll not be able to override the filesystem by hacky injection, so you're going to need to specify a filesystem class via config.ini.

You'll also probably want to implement CDNStorable.
