added condition Params to list to be able to create simple conditions. 
Usage:
                $list = new Example_List();
                if($key = $this->_getParam('key')){
                    $list->setConditionParam(" `key` LIKE " . Pimcore_Resource::get()->quote("%" . $key . "%"),'');
                }
                $list->setConditionParam(" `date` >= ? ", $this->_getParam('creationDateFrom'));
                $list->setConditionParam(" `date` <= ? ", $this->_getParam('creationDateTill'));
