Display proper file icons #71
Description
Currently, Jaya displays its own generic icons for files, folders, drives, etc.. I think it would be better to show the platform-provided icon wherever possible - this would allow, for example, different file types to show an icon corresponding to the program they are associated with, as is the case in Windows's own File Explorer.
Additionally, we should optionally be able to show thumbnails for image files, and ideally, even show the "customized" thumbnails certain programs generate for certain file types associated with them, such as how associating *.PDN images with paint.NET allows paint.NET to generate thumbnails of *.PDN images to display in File Explorer. I believe some versions of Blender do something similar with 3D projects in *.BLEND format, though I'm not certain of this.
