Restructure code following the aftermath of the demo screwup

[joshhting]

• Remove switch statements
• Have player count option on previous scene rather than the player config scene
• Remove switch statements

[strburst]

Is it safe to close this issue?

[joshhting]

Are the switch statements gone?

[jgkamat]

@rmkeezer close if you removed the switch statment, otherwise open n more issues where n is the number of case statements.

We have officially switched to being switch-free
