v7.0.0

Breaking changes:

• Drop support for Node v10
• Drop support for Webpack v3 (things should still work, but you might have to tweak some webpack config)
• Custom functions in jsdomOptions are now merged with defaults (instead of just overridden). If you have a beforeParse function configured, both the default beforeParse and your custom function will be called. Thanks to @konstrybakov!
• The env variable HAPPO_IS_ASYNC, which you can use to control whether or not to wait for screenshot results in CI, is now "true" by default. If you rely on a comment posted with the Happo result, you need to set HAPPO_IS_ASYNC=false before starting your happo run.

New features and other improvements:

• Support for static happo runs where you bundle your happo test run yourself. See https://github.com/happo/happo-static for more info.
• Check with happo.io server first to see if assets/static package needs to be uploaded.

Chores:

• Replace deprecated request library
