Merge branch 'cbeams'

* cbeams:
  Reorder methods in BitsquareEnvironment for clarity
  Introduce 'app.version' property and remove hardcoded version
  Use Preconditions#checkNotNull vs. #checkArgument
  Rename name, port properties to node.name, node.port
  Remove unused ApplicationPreferences variable
  Rename config file from bitsquare.{conf=>properties}
