Sufia 7, ScholarSphere 3.0 thumbnail survey

Info

Blacklight render_thumbnail_tag requires an image, because it only displays the thumbnail if it is an image
By default the thumbnail is using render_thumbnail_tag
Want to use Font Awesome over images because they render faster(?) and there is no additional image creation. Perhaps use SVG and ditch the font files.
Review work and collection icon PR from Sufia: https://github.com/projecthydra/sufia/commit/cde8f5948b11c2d84c9b2b63a1205ce18c9e57af

How do we remove the other overrides????

Where do we display thumbnails in the system and when they are using the default item is it an icon or an image.

Thinking about using thumbnail service
Part of presenter
Look at the view code for thumbnail path service
concerns on how raster versus svg is handled
thumbnailpath service is using the indexer
first replace work.png with work.svg
second update for collection thumbnail service
third nuke the font awesome icons and reduce the number used
fourth would be to make everything use the thumbnail path service for defaults
scholarsphere_thumbnail service, takes the presenter, give you the appropriate thumbnail path (modeled like CC thumbnail), extends CC thumbnail path service
