Color Persistence for Nightly Games (#881)

Added color persistence between game switches for most of the games in the nightly that needed it:
- Basketball Girls
- Bouncy Road
- Chameleon
- Clap Trap
- Fillbots
- Frog Princess
- Sick Beats
- Sumo Brothers

Slot Monster has none yet, because its color changing is a little different lol
