Fix to oneye/oneye Issue #2

 * Upon finding width, height or maximize values in the relevant xml file for an app, $this->cent was being set to '0' on that app's Window widget, even if no values for x or y existed in that file.
 * Code now checks for saved x or y values before setting $this->cent=0
