dhondta/rpl-attacks: RPL Attacks Framework

Stable version.

NB:

• Added versions and update commands
• Fixed a few bugs regarding the tests
• Fixed a few bugs in parser.py (junk tabulation + bug introduced by another fix), thanks to flsubaei.
• Fixed kill command and task termination at keyboard interrupt.
• Some little issues were fixed (e.g. a bug in setting up the framework for mote relationships logging, necessary for building animated GIFs of the evolution of the Wireless Sensor Network).
• Test coverage is poor yet. That's surely a TODO for the future.
