Ian 1b67de854d fix nasty bug with high PHP versions 
@garvinhicking
May this be the "real" cause of http://board.s9y.org/viewtopic.php?f=10&t=20639 ff, not loading the editor.js file? He is using PHP 5.6.17.
What I do not get on this: Why does this only happen with the Standard Editor on his site? And why does this not happen testing both groups to me locally with nearly the same PHP version?

* group_by (string) Can contain a SQL statement on how to group the query. Plugins can also set this, pay attention!
* returncode (string) If set to "array", the array of entries will be returned. "flat-array" will only return the articles without their entryproperties. "single" will only return a 1-dimensional array. "query" will only return the used SQL.
