Remove jingo.views and tests. Fix #2.

With the changes since #2 was filed, it's no longer necessary to have
jingo.views.direct_to_template at all. Django's direct_to_template view
works just fine with jingo.Loader.

I cleaned up some tests, but jingo.render_to_string is still a different
function than django.template.loader.render_to_string, so I wasn't able
to drop that.
