CSS optimizations are conservative in the presence of extra attributes

[GoogleCodeExporter]

What is the expected output?   All CSS combined or cache-extended
What do you see instead?  Some CSS files are left unoptimized
What version of the product are you using:  X-Mod-Pagespeed 0.9.8.1-215
Which version of Apache?  Apache/2.2.3 (CentOS),  X-Powered-By  PHP/5.1.6
Please provide any additional information below, especially a URL or an
HTML file that exhibits the problem.

These links are not optimized because mod_pagespeed ignores any 'link' tags 
with unexpected attributes.  It should just leave them alone -- actually 
CSS-combining should probably *not* combine CSS links with distinct IDs.  
However that should not prevent cache extension.

The restriction for combine_css still remains, but combine_css and rewrite_css 
no longer are affected by extra 'link' attributes.
