Add Local Development Automation Tools

[jalcine]

Using Guard

To make local testing a bit faster (instead of having to go through a REPL
loop), adding guard with guard-shell would allow for easier testing
feedback.

• Add git hooks to Wintermute.
• Add unit testing listener for wintermute-core.
• Add coverage reporting logic for wintermutec-ore.
• Add auto-documentation generator for wintermute-core.
• Add Rack server to:
  • listen to documentation folder and serve content for
    wintermute-core.
  • listen to generated coverage files and render HTML content for
    wintermute-core.
  • Add livereload support to allow for updating of HTML content in
    real time.

Other Chores

• Move all of the Git hooks to be under a rake command, i.e: rack git:hooks:bind

This is going to be a PITA to build out, but once it's done, things'll move
quite a lot faster.
