Beginnings of the "pass everything using a native type wrapper" console code.

- ConsoleValue class is now the base value class.
- ConsoleValueRef is now used to supply function parameters. Values are disposable.
- Script functions return values instead of just strings where possible.
- Variables can be disposable strings
- Bytecode changed

Fix the issues with console method parameters and fields which prevented missions from loading.
