Minor 404 errors in Admin in web-server log due to List Arrow images

There is a little glitch when we get additional 404 errors due to incorrect paths for List Arrows on some sections in Admin.

This is a log records from web-server:

AAA.BBB.CCC.DDD - - [04/Jan/2011:10:05:26 -0600] "GET /dev/SVN/5.1.x-dev/core/admin_templates/%5C%22img/list_arrow_desc_big.gif%5C%22 HTTP/1.1" 404 7132
AAA.BBB.CCC.DDD - - [04/Jan/2011:10:05:26 -0600] "GET /dev/SVN/5.1.x-dev/core/admin_templates/%5C%22img/list_arrow_desc_big.gif%5C%22 HTTP/1.1" 404 7132

This happens, because we've got relative paths to images in grid_blocks.tpl and that code is evaluated in javascript resulting base url to be added.
