function ChartsOpenFlash::_preprocess_values in Charts and Graphs 7

Same name and namespace in other branches

Pie-chart has different format for $values array than bar chart etc. This method deals with permutations across chart types. Sigh.

<p> We also remove items with no label, while we are at it, since those can cause problems to Flash renderer.
