rviz

* Qt5 is now the default build option, but Qt4 support is still available (for C++ only).
* Fixed support for PyQt5, but disabled PySide2 until we get it working.
* The default plugin's library was changed to ``rviz_default_plugin``.
* Changed to use CMake's ``file(GENERATE ...)`` macro when exporting the default plugin's library name.
* Changed costmap lethal color to be different from illegal values.
* Cleaned-up and generalized the WrenchVisual display:
  * renamed ``WrenchStampedVisual`` to ``WrenchVisual``
  * cleanup: removed deprecated API
* Updated the marker display and tf plugins to update the map of enabled namespaces and frames whenever those frames are enabled/disabled using the check boxes.
  Also updated the plugins so that the map of enabled namespaces and frames does not get erased whenever the plugin is reset. (#988 <https://github.com/ros-visualization/rviz/issues/988>)
  This allows the currently selected namespaces/frames to remain selected after the Reset button is pressed.
