cssOptimize path breakage

[dante]

using the cssOptimize=comments on a custom css file breaks the paths.

to reproduce: create a sibling "ns" folder

ns/
   tests/test.css
   tests/test_Dialog.html

the tests.css has:

@import "../../dijit/themes/tundra/tundra.css";

before build, the paths work.

running a build_release-like build (see b1 build) causes the paths to the icons in tundra.css to be refered to in tests.css as:

url(dijit/themes/tundra/images/...)

when it should in fact be

url(../../dijit/themes/tundra/images...)

interestingly, if the test.css is in the top ns, and is referenced by the test_Dialog.html as @import "../test.css"; (and test.css's @import is simply ../dijit/themes/tundra/tundra.css), the path's work after build (if i'm not mistaken).

put in ns/tests/
