0.4.1 (Part 2)

I only added 1 of the 2 planned gamemodes, and released the update WAY too late, as I have been working on other games mostly. 

Changes:

• Complete rework of the level/mode system, for more customization
• Settings are now saved
• Music and SFX volume options available
• Glass panel now has ridges
• Removed lights from pieces to increase performance
• Board Lighting is now baked to increase performance
• Direction indicator material changed to inverting the colour
• Pieces' hitbox made smaller again to increase satisfaction
• Physics game mode from the older versions as gamemode

Known bugs:

• Selection outline glitch from 0.4.0
• Direction indicater can get deleted
