The parsing of those code blocks is handled by ParseCode.
Note on parsing newline characters:
- there should be an implicit linebreak {br} after each dialog line
- a "dialog line" is defined as any line that either:
- 1) contains dialog text (any text outside of a code block)
- 2) is entirely empty (no text, no code)
- *or* 3) contains a list block (sequence, cycle, shuffle, or conditional)
- lines *only* containing {code} blocks are not dialog lines

evidence that the parsing system kind of broke down at this point :(
Maybe it would feel better if I move into the "state" object
