Implement Control Flow

[Ratstail91]

• if-then-else
• ternary ?:
• while
• do-while
• for
• foreach (compounds)
• continue
• break
• switch-case-default (and continue?)

Potential Opcodes:

• JUMP
• JUMP_CONDITIONAL (true/false)

I'm not sure how a switch statement could be done efficiently, so it'll need research.

I did some thinking about this yesterday.

I started working on if-then-else a few days ago, but the tests aren't finished yet due to unrelated bug hunts.

The control flow for break and continue requires arrays to keep track during compilation, so #155 needs to be finished first.
