Costumized Lucene Search Page

[Michael Guntli]

With RC1 lucene seems to work again, so i have costumized the existing search
form from jkraemer
(http://www.jkraemer.net/static/maven/xwiki/plugins/lucene-plugin/install.html)

But keep attention: it's just a quick&dirty example to display the results
in a table ;-)
As im not very familiar with velocity, the code is quite ugly! (for example
i didn't find a while loop to output the number of stars for score-quality,
so i did it with if, if, if..)

it still has some bugs:
* if you search for a regular expression (e.g. win*), then the query for the
next page will be win</strong>
* non wiki-documents and non-attachments will be hidden from the results, so
it could happen that you see an empty page with a link to the next results
(that's because searchresults.hitcount returns all results, also the hidden
ones..)
* many more..
* icons are hard-coded.. (/skins/lgs/*.png)

You can get the icons for free from famfamfam:
