PickList always applies style class PickList.SOURCE_CONTROLS

[lxs]

PickListRenderer#encodeListControls, line 129:
writer.writeAttribute("class", PickList.SOURCE_CONTROLS, null);

It should use the "styleClass" parameter which has been passed in. The result is style class "ui-picklist-source-controls" being incorrectly applied to target controls.

This is causing PickList#setupButtons in picklist.js line 100 to not match a jQuery expression, leading to iconOnly not being applied and nonfunctional buttons.

I'll open an issue.
