eslint-plugin-html v2 compatibility

[BenoitZugmeyer]

I am about to release a new major version of eslint-plugin-html and it will not export processors anymore, so this won't work anymore. Of course if you don't change your eslint-plugin-html dependency version everything will be fine, but I don't plan to maintain the v1, and the v2 has long awaited features like the eslint --fix support, which might interest you.

My plugin isn't exposing processors anymore because the current eslint system is too limited (e.i.: doesn't support --fix), and I wanted users to be able to configure the html file extensions they want (most of my plugin PR was about adding new file extensions). Instead, it patches some ESLint functions as soon as it is required. It seems scarry but it already did it from the beginning and it worked correctly since then.

So one solution would be to simply require("eslint-plugin-html"); in your plugin and that's it. .vue files are already considered as HTML by default, but if you want to override the default to only lint .vue files, you can add the following setting in eslint-config-vue:

    "settings": {
        "html/html-extensions": [".vue"],
        "html/xml-extensions": []
    }

See documentation and changelog. I released the v2 as a beta tag, so you can try it with npm i eslint-plugin-html@beta.

Let me know if you have any concern about those changes.
