D8 Port

Yeah, that'd be great.

As suggested in the core issue, I'd try to port this module to D8 and then look, what parts we can suggest for core.

There's a first patch that seems to work fine on my local drupal 8 dev.

@Ian, I've split up the whole patch in several commits in my local repos, so maybe (if you like) I'd open a sandbox or may get access to this module's repo, so I can directly push the history.

btw: there currently is a core bug that prevents relying on views theme handling: #1911492: Views try to find Custom StylePlugin template in core/modules/views/templates. Therefore the hook_theme_registry_alter() had to be implemented.

Patch applies nicely. Haven't been able to test the module though as Core is failing on me right now.

Ok, I finally remembered to nix the /c directory that is now getting created in D8. Then went to re-install and everything went fine.

After installing the updated Views Responsive Grid in D8 though I couldn't get it to show up in more than one column. Played around with it a bit, but wasn't able to get it to do anything in 3-4 columns. I might have to read the docs.....

Anyways, also ran into this PHP warning:

derhasi - I applied your patch in the 8.x-1.x branch and made you a maintainer

Committed to the 8.x-1.x branch: b8478cc.

This is just in-case #1903746-42: Replace the views grid table template with one using divs doesn't make the cut.
