Non-spatial file types (PDF, images, etc.) not filtered correctly

[OwenGeo]

In March 2013, the capability to add other file types to ArcGIS Online was added. This included files like PDFs, Word/Excel docs, and images.

When you find these files in searches or view them on a Group page, these new file types appear under the "Maps > All Maps" filter option. They should not appear when looking for maps, and there should be new filter categories added. Something like:

Files > Documents and Presentations (PDF, Word, Excel, PowerPoint, etc.)
Files > Images (JPG, PNG, etc.)

So the higher level filter categories could be:

All Results
Maps
Application
Tools
Files
