This does a number of things.

• Gets rid of Rick :-(
• Puts the Toast drum track back in
• Creates a second frame counter for loop timing that can be reset to avoid overflow errors but...
• that approach was unsuccessful - game is less responsive with a high count there, but it might still be useful elsewhere
• Introduces a "toast ticks" parameter - toast values are only updated with this period (in ticks ie iterations of game loop)
• Slot values updated continuously so game is smooth, but toasting is slowed down (and can hence be speeded up!)
