Build #2 Released

Important changes :

• New (re)triggering logic. Triggers are now tracked per-ball. Each ball can fire a given trigger exactly once. Kangaroo no longer resets which triggers have been fired.
• Added Laballatory! This is a free build/play mode. Mainly used by me for debugging, but you can also use this to test some theorycrafting :)

General changes :

• Add main menu, music, and volume controls.
• Added support for "right click to cancel" while placing a trigger.
• Fixed the rendering of scores in the score tray. All triggers should render their score properly now.
• Fixed a class of bugs where score multipliers weren't applying to triggers with special logic. e.g. Plate was not multiplying toasted Bread. This is fixed now.
• Added a small sprite thumbnail to show which ball hit each trigger in the score tray.
• Fixed a bug where re-bonked bumpers were not playing the thud sound.
• Changed base payouts of Common/Uncommon/Rare/Mythic items to 5/10/25/50. It had been 1/5/10/50 before. $1 items just felt too inconsequential.

Trigger changes :

• Lucky Charm is now Very Lucky Charm, is Mythic instead of Rare, and triggers Rainbow 75% of the time intead of 100% of the time.
• Added Semi-Lucky Kinda Charm, a Rare which also triggers Rainbow, but only 50% of the time.
