Fix Add-on store problems

[magicus]

Converting the config.json to config.yaml seems to be the first step towards resolving #256. There seems to be additional hurdles, though.

Ok, this patch more or less works now (as far as I can tell; it installed the Add-on on my system). There is one problem that I did not know how to best resolve, though. For logging purposes, the information from config.json were read into an AddonInfo object in Configuration.js.

But now the file is in YAML format, so the JSON.parse() method will not handle it. (I presume)

I have some ideas on how to resolve this, none is ideal so I'd like feedback, and/or that @icanos takes over this PR and fixes this part.

1. Keep a copy of the info in config.json as well
2. Keep the format in pure json even if the file is named config.yaml (this is legal but not recommended)
3. Skip the logging and remove this code
4. Add a yaml parser, like js-yaml to the installation (this is the preferred option I think)

Has there been any more progress on this to get it to show up in the Addon Store?

Ok, after a reboot or two it all of a sudden showed up

@e120guru @magicus - so... It IS showing up without the need for the requested change in the linked PR?

I honestly don't remember if I managed to get it working without this patch, or if I am still running a patched version on my hass installation, based on my personal repo. But if other users get it to work without the patch, I guess it is not needed.
