Add type and mutli-page icon indicators to DAMS cards

[wrenaria]

Add icons to cards in Search result view to indicate content type (if not an image) and multi-page items.

Use designs from v3 version.

(Old, original issue: UCDavisLibrary/fin-server#143. Different designs for v3.)

Type and multi-page indicators will appear as icons in a semi-transparent aggie-blue tag in the lower right-hand side of item images. I updated the icons for this so that they will transition seamlessly to the future v3 brand updates without any need for changes.
