New ways to earn Codepoints + Terminal Cleanup

Alrighty. This one's a small one.

I've ported the two beginner apps from UltraDOS that helped you earn
codepoints (scriptpoints in UltraDOS) to ShiftOS-Next.

I've also moved some Terminal methods like AddLine() to an API.vb
module. I've also hid the MathQuiz and GuessTheNumber code in the
TerminalGames module.
