IceBeats v0.3 Beta

We're getting closer to v1.0..! Pushed to production.

• Color palette changes now smoothly fade
• The current palette's hue now wavers a tad vaguely to the beat
• Lots of polishing of the bass LED strip effects, including a second bass strip visualization and more bass strip config options
• Improved bass kick effects in some visualizations
• Light test now tests all connected LED strips
• Added meme output - Stepmania's two bass neon outputs are xor'd together to get another electrical output on a shift register. Since SM doesn't seem to turn on only one neon normally, this is solely controlled by simfiles with lights charts that turn on only one bass light at a time.

TODO: Still gonna do a bit more polishing, namely mod a few things that still look like unicorn farts.
