Start of mini_installer build config refactoring.
Baby step one: 
- All intermediate files go into the intermediate directory.
- The packed_files.txt file is gone, and instead the mini_installer
  is baked from a resource file output into the intermediate dir.
- Cleanup use of implict global "options" in the python script.
- Use subprocess.call with a list instead of os.system.
