ximport is really silly and shouldn't be used

All this does is import a module from a path. Well, this is easy to do in python:

import imp

def load_module(path):
filename = os.path.split(path)[-1]
module = filename.rsplit('.', 1)[0]
return imp.load_source(module, path)

This should also go in e.g. utils and not its own module
