[Typo3] Solution for cm_jstickernews stopped showing newsheadlines

[Christoph Kammermeyer]

This refers to a thread posted on July 1st concerning  cm_jstickernews and 
newer tt_news versions. I had the same problem and found the following 
solution:

Replace line 502 of pi1/class.tx_cm_jstickernews_pi1.php
by:
$cat_select = " AND cat.uid_foreign IN (".$this->conf["newsCatList"].")";

and line 520 by:
$query = "SELECT * FROM ".$table." left join `tt_news_cat_mm` cat on 
(tt_news.uid=cat.uid_local) 
".$news_select.$cat_select.$this->cObj->enableFields($table).$orderBy_limit;

This modified query uses the tt_news_cat_mm table to fetch the results.
