Savable bytecode

[alekratz]

This would be a nice feature to have, since every time we pull in files they get parsed/compiled, which becomes redundant if you're just updating one file at a time.

Caveats/considerations:

• Do we store debug/file symbol and information? (e.g. source path + location where each bytecode instruction gets generated from) Will we support stripping of this information?
• Compiled file names and detecting when to re-compile and import *.sblc (or whatever the extension is)
  • Imports are done by direct path, which needs to be taken into consideration.
• General file format
