Modification to the Communication framework API.

Browse source 
- Simplified the communication API and made it easier to change
  to encrypted connections by not having separate variables to
  define encrypted and unencrypted ports.

- Now, to enable listening without configuring nodes just
  load the frameworks/communication/listen script.

- If encrypted listening is desired set the following:
	redef Communication::listen_encrypted=T;

- Accompanying test updates.
