Performed a large refactoring

Performed an extensive refactoring on the entire application for the
sake of code-cleanliness.

- Refactored out of an ad-hoc Imperative paradigm into more of a
  functional/declarative paradigm. IMO, this makes the application
  signifcantly easier to understand.

- Moved away from `argparse` and into `docopt` for argument parsing

- Version bump to 2.0.0

- Performed extensive refactoring on the setup.py script. Script should
  install to the system more cleanly now.

- Made minor formatting changes to the --list flag output

- Updated the README

Squashed commit of the following:

Bug fix

Previously, cheat would crash if the DEFAULT_CHEAT_DIR was not set. This
should resolve that issue by creating the directory if it does not
exist.

Improved filesystem efficiency

Previously, `sheets.print()` would query the filesystem every time it
was invoked. This was inelegant, because it is called multiple times
every time `cheat` is executed. Thus, unnecessary calls were being made
out to the filesystem.

Now the result of that function is being buffered into a module variable
when it is executed the first time, and served from there thereafter. I
broke the "functional" paradigm to a degree by doing this, but it wasn't
worth the complexity of implementing proper memoization (decorators,
etc) for such a trivial case.

Bumped the version number accordingly.
Added a CONTRIBUTING.md file

- Added a CONTRIBUTING.md file
