backend speed: added icon info cache for speed improvement of the directory view ('view' event): now all icons are 'calculated' only once; any further requests for the same (directory, image, etc. icon) are fetched from cache. (This is part of the 50 --> 13 second 'view' performance improvement for the 9K+ files' directory.)
