commit 6fb1d109b8f0476d92cfee10784f1a4795c26e08

    Make GTK & async unit tests work by running them in a GTK+ main loop.
    
    Include GResources in the build so they can be loaded.
    
    Bug 776421.
    
    * test/main.vala (main): Init GTK, start a main loop and run the tests in
      that.
    
    * test/CMakeLists.txt: Include GResources in unit test binary so they can
      be loaded by tests, and since we can't compile them into the client
      static lib.
