Fixed SEGFAULT when no Createfile, doc changes and cleaning up

! A segmentation fault was caused when the program tried to open
  the Createfile, but could not. Now abort with an explicit error
  message instead.
- The documentation referenced to my project BaseOS on some spots.
  These references were removed, as I don't plan to work on it too soon.
* Errors corrected in the documentation. References to nonexistent
  features were removed.
- Removed a much-too-stiff install target - please install manually
+ More debugging messages with undocumented DEBUG constant
+ Added newlines at ends of files

I promise to add something like a test suite for this system soon.
