Another GUI update

This time the flickering should be much less noticeable and the icons are (after you deleted the cache folder) not squished anymore.

Developers:
You can now open local directories, where you backed up your files in the format:
(?<prod>[0-9]{8}|[0-9]{2}-[0-9]{4}) - (?<audio>[0-9A-F]{8}) - (?<name>.*)
You don't understand this? Then just ignore it :)
