Post jam update

There’s a few updates. I improved the UI a bit, added more variation to the music generation, and added a proper build system to make any future updates easier.

Here’s a list with most of the updates.

• Randomizable synth presets
• Changed control knob image
• Updated color scheme
• Added chord arpeggios
• Added proper intros and outros for the generated music
• Increased verse and chorus variability
• Changed chord progressions to be completely randomly generated
