Faster music mastering, and more

Auto Master is now faster!

In my extensive testing, I've consistently found the new version to be 3x faster with a 4 minute song taking between 3-4 seconds!

Here is a complete list of improvements:

• Faster music mastering, ~3x speedup
• Many audio formats are supported - while WAV is still recommended, you can also use MP3, OGG, FLAC or AAC
• Many sample rates are supported - your audio will be automatically converted to 44100 Hz before processing
• Improved UI - this is subjective, but I've been told the new UI looks better
