Style Changes

Try to standardize style. 4 space indentations, if / else on same lines
as brackets, etc.
Move config to file
Add .gitignore and package.json

Make setting up katelibby just a bit easier.
Add command module interface

Simply drop a JS file into the “command” directory and export a
function. See command/test.js for an example.
