3.0.0 Beta 1

This update contains breaking changes:

The plugin now uses namespaces rather than prefixed class or function names. Any references in custom code to classes or functions in this plugin will need to be updated.

For example to get the plugin class instance change S3_Uploads::get_instance() to S3_Uploads\Plugin::get_instance().
