Changes in api and upwards

- Removed out-of-stack error reporting
- Revised module system to match previous Orchid system
- Errors are now in a Vec everywhere
- Implemented atoms and lexer
- Started implementation of line parser
- Tree is now ephemeral to avoid copying Atoms held inside
- Moved numbers into std and the shared parser into base
- Started implementation of Commands
