“progress” class name causes conflicts

Hello! Thanks for the great plugin. It does exactly what we need. I found that there was a conflict with the Seriously Simple Podcast plugin because both use the class name “progress” SSP has changed there code so their plugin no longer conflicts, but it would be great if you could update your code with a more specific class name as well. You can see the conversation on their forum: https://wordpress.org/support/topic/plugin-conflict-starting-with-2-5-0-progress/
