// -----------------------------------
// Converts span tags with the class 
// icr_fl (fl = fakelink) to hyperlink
// -----------------------------------
// Remarks: 
// Some navigation links do more harm 
// than good for SEO (duplicate content, 
// keyword spamming, pagerank dilution,
// etc.). This is a legal way to keep 
// crawlers from following these links 
// (same content for crawler and visitor)
// and counting them for pagerank point
// (instead of the rel=nofollow attribut)
// 
// In SYC these links are found in 
// the tagcloud, sorting options, 
// paging, etc. These links are great 
// for visitors, but terrible for SEO.
