Pronto 0.6.0 support

[mmozuras]

Hey,

I've released 0.6.0 of Pronto this week. There's one breaking change you have to be aware of:

Runner expects to receive patches/commit via initialize(patches, commit), instead of run(patches, commit).

Here's an example of how to implement that change in the Runner:
prontolabs/pronto-scss@c9fa316

You can also now pass the Runner class as a parameter to Message.new. Here's how:
prontolabs/pronto-rubocop@f19d886

I think that it's worth implementing both 😄

Oh, just noticed it today. Will update it some time soon.
