[Perlfect-search] stop highlighting of ignored document parts

[Morten Wulff]

First of all, a big 'thank you' to Giorgos and Daniel for a great piece of 
software!

On one of my sites, some of the most popular search terms were also used in 
the site navigation. I put all navigation elements between 
$IGNORE_TEXT_START- and $IGNORE_TEXT_END-tags. Unfortunately the text in 
the navigation elements were still highlighted.

So, I've taken the liberty of making a small change to search.pl to fix 
this problem. Please correct me, if I've made any blatant mistakes ;-)

Diff against latest cvs version below.

Regards,
Morten Wulff
