Comment (by iwakeh):

 Some remarks about the `Configuration`:

 * using the enum name instead of the string name of a property makes sure
 there are no nonexistant properties in tests and guards against typos,
 i.e. `Key.BridgedescsActivated.name()' instead of the string
 "BridgedescsActivated"
 * `Configuration` exends `Properties`, for example in `SchedulerTest`:
  {{{
   private static final String runConfigProperties =
 "TorperfActivated=true\nTorperfPeriodMinutes=1\nTorperfOffsetMinutes=0\n"
     + "RelaydescsActivated=true\nRelaydescsPeriodMinutes=1"
     + "\nRelaydescsOffsetMinutes=0\n"
     + "ExitlistsActivated=true\nExitlistsPeriodMinutes=1\n"
     + "ExitlistsOffsetMinutes=0\n"
     + "UpdateindexActivated=true\nUpdateindexPeriodMinutes=1\n"
     + "UpdateindexOffsetMinutes=0\n"
     + "BridgedescsActivated=true\nBridgedescsPeriodMinutes=1\n"
     + "BridgedescsOffsetMinutes=0\n";

   @Test()
   public void testSimpleSchedule() throws Exception {
     ...
     Configuration conf = new Configuration();
     conf.load(new ByteArrayInputStream(runConfigProperties.getBytes()));
     ...
  }}}
