parinfo -> as_Parameters fixed to use kwargs instead of relying on order of
arguments.  However, according to the git history of lmfit-py, as_parameters
(and therefore the lmfitters within pyspeckit) *never* worked an should
*always* have crashed.  The fact that they didn't is perplexing and deeply
disturbing.
runtests -> run_tests (no wonder they were failing...)
fixed test paths
travis dependency fix
trivial change; import test_units in tests/__init__ (but there's no reason this should change any behavior)
travis update (install first) - is this a bad idea?   Is the syntax wrong?
another travis update; no idea if it will have any effect
savedir fixes for when savedir is inappropriate / boring
added setuptools to setup.py, but ONLY if develop is used
BUGFIX: cubes correctly processes BUNIT
added a new NH3 cube example
added NH3 cube example
added nh3 cube example html
