Finish overhauling animation module to support waiting states

• ISRU Animation module now will optionally wait for the current looping animation to complete before changing states, making transitions look more seamless
• Better looping animation handling, instead of manually refreshing animations
• Better documentation
• Remove some debug code in HeatEffects
