allow for "folderish content" that isn't a folder

the current execution does not handle content that is folderish in a usable way.  as an example, for SAI, they have configured a picture object that is folderish.  With the current connector, the panel sees this as a folder, not a picture. 

 

We have seen this also, with direct edit/drive in the past.  Request is to use the file:content to determine the file object.  If no content then we should look to the folderish facet.
