rqt_reconfigure: After filtering, node selection gets reset even though some nodes were selected

[130s]

Possible bad situation: node boxes are shown on right-hand side but their item on left-hand is not selected. When user selects a node on LH, the corresponding box disappears from RH.

I described the problematic phenomenon in the question on stackoverflow (satisfactory responses from there can help solving this issue too).

Related to issue #17.

Although this issue is not yet fixed, it becomes more trivial with 2420b6e. Set to untargeted.

This hack (https://github.com/ros-visualization/rqt_common_plugins/blob/groovy-devel/rqt_reconfigure/src/rqt_reconfigure/node_selector_widget.py#L227) should be removed to avoid any non-synchronous behavior of the left and right column. After that the behavior should be modified that selections are always remembered even when a filter temporary hides them. After removing the filter the selection should be restored.
