- VM now prompts for filename to load bytecode from
- Added new EightBall disassembler (`disass`), removed disassembly printout from compiler
- Fixes to interpreter / compiler error reporting. Should no longer report completely incorrect line numbers!
- Added new immediate mode VM instructions for load (`LDAWI`, `LDABI`, `LDRWI`, `LDRBI`), store (`STAWI`, `STABI`, `STRWI`, `STRBI`), and flow control (`JSRI`, `JMPI`, `BRCI`). Modified compiler to use these new instructions. This significantly improves code density and VM execution speed.
