Suggestion fix for ikiwiki search results

[Daniel Bond <db@xxxxxxxxxxxxxx>]

Hi,

on the DragonFly ikiwiki, search results include navigational  
elements, from the parsed markdown output.
One example is:

http://www.dragonflybsd.org/wiki.cgi?P=dma

I think search results could improve if we installed a modified  
IkiWiki/Plugin/search.pm. I'm not exactly sure how Ikiwiki includes  
it's plugins,
but it might be possible to install it into a directory that has  
higher presence in the perl search path ( perl -e 'print qq(@INC)' ).  
This way it won't
conflict with pkgsrc.

I wasn't able to remove entire <div>..</div> blocks, with  
HTML::Scrubber, so I replaced it with HTML::TreeBuilder. I'm no Perl  
guru, so there
might be better libraries? Also, I wanted to keep out of the other  
plugins way, so I didn't want to redefine $scrubber as a different  
object.

The code has not been tested live in Ikiwiki, I tested it by saving  
the output of ikiwiki, and piping it through equvilent code, so it  
might need some
minor adjustmenst. If people like the idea, I can setup a test  
environment of Ikiwiki in my homedir on leaf and test it further.
