[phoenix-dev] Addition to ProjectInfoValues class

[Karl Matthias <karl.matthias@xxxxxxxxxxx>]

I discovered that if you need to iterate over the fields in the 
ProjectInfoValues class without knowing ahead of time what they are, 
it's pretty hard.  I added a function that will allow you to do that:

   function fields() {
       $fields = array();
       foreach($this->rows as $row) {
           $fields[] = $row['SubKey'];
       }
       return $fields;
   }

Pretty simple, but quite helpful.  Shall we add this to the phoenix cvs?
