Dev release 0.50b

Important: We are now distributing a pre-compiled version of the mod. However, for modifying difficulty, it is still recommended to compile the mod yourself.

New features:

• Added ballchains
• Added scoring API and default score module
• Added BLOCK and NOTE events for traffic blocks and meteors respectively
• Added debug display for tracking without a VR headset

Bugfixes:

• maxAccel now does what it's supposed to - limit max accel
• You finally get a score, no more wasted tests
• Fix very long armspans in doubles
• Purple notes now generate like a doublenote

Known bugs:

• There are a little too many doublenotes - may need to play with values
