Machines not displayed

[heuristicus]

The following shows the turtlesim node, but not the machine. setting default=true on the machine populates the machine field in node properties, but still does not display the machine in the tree.

<launch>
  <machine name="turtlesim_machine" address="testaddr"/>
  <node pkg="turtlesim" type="turtlesim_node" name="turtle"/>
</launch>

The setHidden() function on the QTreeWidgetItem is never called with True for machines in filter_launch_entry, which is why they are hidden.

Apparently forgot about those as there is no separate "machine" checkbox (and I don't think it makes sense to have one).
