Plugins causes failure when eclipse is run in a headless mode

[truhlikfredy]

When building in a headless mode the whole build works fine and when it's finished in the end it will fail here:

Looks like the plugin always assumes the display to be present: https://github.com/kwin/cppcheclipse/blob/master/com.googlecode.cppcheclipse.ui/src/com/googlecode/cppcheclipse/ui/Console.java#L84
