cursors for panels

cursors for panels

BH note to self: JSComponentUI was using ui.domNode instead of
ui.outerNode. For a panel this is an empty node inside the outerNode,
which is what holds all the children. So the cursor was being set, but
the children did not inherit it.

Also missing some cursor names; now set to draw cursor names from
JSToolkit. But note that JSToolkit.setCursor should not be called.
