Title: Fix crashes for all plugins inheriting from MessageFilter

Fix in `MessageFilterDisplay` base class to call the `processMessage` callback via a QT signal. This fixes a bunch of RViz crashes when running RViz as part of rqt.

`MessageFilterDisplay` now keep a shared pointer to a received message, but no additional copies of the data are made.
