Title: Grab knife path from environment or options hash if possible

This addresses https://github.com/racker/dreadnot/issues/18. Default knife path is still /usr/bin/knife, but the default can now be overridden by setting KNIFE_PATH in the environment, or setting the knife_path key in the options hash when calling the knife() function.
