Another bad commit

Lots of changes here...

- Removed code using RecursivExtractor due to bad usage of /tmp
  Note: the code that used RecursiveExtractor may not have been in the
  previous commit
- Created _functioning_ implementation of DebUnpacker
- Restructured Project layout.

TODO:
- Possibly rewrite how the DebUnpacker works to have the file contents
  part of an entry.
- Further restructuring and refactoring to make the code a little
  neater.
- Add code for the final unpack steps Un-XZ -> untar -> write to disk
- Add code to install
- Add code for modified post-install pre-remove etc..
  This is kinda needed to ensure proper system integration of new
  packages.
