release: 2.0.0

[adampash]

This is a full version bump. The signature for Mercury.parse has changed from:

Mercury.parse(url, html, { ...opts })

to:

Mercury.parse(url, { html, ...opts })

Basically to keep the API more flexible for adding new options in the future, we're moving the optional html argument inside the options object. This will prevent a lot of unnecessary Mercury.parse(url, null, { foo: bar }) calls in the future.
