Fix links and Travis

[tucked]

This also configures Travis for automatic deployment to PyPI when tags are pushed (the stylistic changes to .travis.yml were done by travis).

maybe we should just fork this project?

[tucked]

Ya... This definitely feels like a hack. I'm not too worried about it since it's test code, but if that fork ever goes away, it will break anything that ever depended on it (e.g. we won't be able to rerun old Travis builds). I think we can use the same commit from the original repo since there's a PR open for it (rjancewicz/python-kadmin#59). At least if that goes away, we'd probably need to find a more permanent replacement anyways.

Actually, that doesn't seem to work:

we won't be able to rerun old Travis builds

As it is, python-kadmin is not used in Travis because a KDC would be required.
In fact, it's only used in 1 place (for cleanup):

isilon_hadoop_tools/tests/conftest.py

Lines 354 to 355 in 29d9936

	# Delete the principal.
	kadmin.init_with_password(admin_principal, admin_password).delete_principal(principal)

I'm gonna leave it for now, but I've asked the publisher of kadmin if they will publish the commit we're using. Let's keep an eye on it.

Travis looks happy now.

LGTM!
