Initial (buggy) implementation

- Implements modular computers, starting with single program (power monitoring console)
- Implements most hardware. Some is still TBD, but the important stuff is in place
- Implements file-based system. Currently two file types exist, programs, which have NanoUI/Topic() interaction with user and data files, which may be used to store string of data.
