Allow the use of icon class names instead of image URLs in places.
Review Request #4350 — Created July 20, 2013 and submitted
Allow the use of icon class names instead of image URLs in places. The datagrid columns and inlineEditor now accept class names representing icons for column and edit icons. These can be used instead of URLs, for applications that use spritesheets.
Tested with an accompanying Review Board change that makes use of spritesheets.
