Got basic bh command working

- Setup tools will run bh now.
Got bashhub-bh works from python install now

- renamed Command.py to command.py
- split MinCommand into its own class.
- upped jsonpickle's package version
- removed that shitty sys import crap. Should just need to import things the
  right way from the modules.
Updated .gitignore
Added shell scripts and configured install via pip

- should be able to install with pip install . and it configures
  the scripts in your home directory.
Added model directory to MANIFEST
Fixed install directory to be in .bashhub/
Added find packages to setup.py
Removed some unused imports
Only add source hook if it's not present
Added bashhub_setup and bashhub.py

- Need to clean these up still. making bashhub.py into cli app.
WIP right now to install env
WIP

Adding a slew of new commands to bh
