Social media icons have moved, but they should also still exist in the old place

[Stoob]

Old location:
uk.co.vedaconsulting.mosaico/packages/mosaico/templates/versafix-1/img/social_def/
New location
uk.co.vedaconsulting.mosaico/packages/mosaico/templates/versafix-1/img/icons/

While I'm not suggesting the images be moved back, I am proposing icons exist simultaneously in both locations. The reason is that even if we update our templates, hundreds of thousands of emails already exist out there 'in the wild' with these old icon links which are broken.
