Fixed handling of IE's 32 CSS file limit.
Fixed handling of IE's 32 CSS file limit.

# In IE up to version 8, there is a technical limitation for < 32
#   CSS file links. Subsequent links will be ignored. Therefore
#   the loader must be activated for delivering CSS to this browser.
#   The loader will concatenate and minify the files, resulting in
#   very few CSS file links.
