Support v2 Linter API

[Arcanemagus]

In the v2.3.0 release of linter support for the v1 API was removed, breaking semver. This means that this provider is no longer supported by the current version of linter.

To get this provider working again it will need to be upgrade to the v2 API, a guide for accomplishing that can be found here: Upgrading to Standard Linter v2.

Until this is fixed in order to use this provider you will need to downgrade to the last version of linter that supports the v1 API, you can do this with apm install linter@2.2.0.
