    More robust unit tests for async.idle(alwaysQueue=True). Also using a single
    wx.App object for complex reasons

    Adjustment to async.idle(alwaysQueue=True) - now, a second idle call is only
    necessary if the first call came before a wx.App had been created.

currently dirname has to be output as the first line, as loadLabelFile will
crash on files which don't have it.
