Create a new release to support phoenix 1.6.0, phoenix_html 3.0

[abstractcoder]

Master is already compatible so can you create a new release so I can upgrade my dependencies?

I would also be very interested in this!

Current workaround:

{:phoenix_slime, git: "https://github.com/slime-lang/phoenix_slime.git", branch: "master"}
