cm: Replace Grunt/RequireJS with Gulp/Browserify. Yes, I know, this sounds like it's 2014 or something, and cool kids are now actually on webpack or whatever. Anyway, besides the change to a `gulpfile`, it also moves all dependencies over to `npm` (via the `package.json` file), which cleans up the repository nicely, and replaces awkward JS imports with simpler `require` statements.

#!/usr/local/bin/python
import sys
import logging
import colorama
from wikked.witch import ColoredFormatter, main


# Configure logging.
colorama.init()
root_logger = logging.getLogger()
handler = logging.StreamHandler(stream=sys.stdout)
handler.setFormatter(ColoredFormatter('%(message)s'))
root_logger.addHandler(handler)
