v0.5.0

This is another big release, with wide range of bug fixes and performance improvements, specifically for local folders. I'm thankful to all the people who submitted issues.

• We now have smart playlists. You can combine different rules as well. Currently this is WIP, there can be more work to do on this.
• You can change the regular seekbar with waveform one. Waveforms are calculated lazily based on the queue to not throttle the performance.
• Implemented a wider range of Auto DJ features.
