jquery-ui is no longer bundled in git repo and is downloaded during
the install or sdist process. If you are installing from pypi the
files will be included, but if you are installing from git you will
need internet access the first time you run pip install .. The
install process tries to cache the files and will not need internet
access on future installations.
