Shorten all dependencies to ~> X.Y about volt

[ryanstout]

@postmodern I thought ~> X.Y.0 was the same as ~> X.Y Am I wrong on that?

[postmodern]

~> X.Y.Z is the same as >= X.Y.Z, < X.Y+1.0

@postmodern Ok, good, thats with I thought. I was clamping them on purpose since some of the dependencies were changing fast (mostly opal). I'll unclamp them on my current dev branch. Might be a little while before it gets pushed.

Clamping opal makes sense. Also if you want to avoid older buggier versions, you can do: '~> 1.2', '>= 1.2.3'
