New tincd post-auth BOF exploit module

A pull request to get some feedback. I'd appreciate if you comment as well on the following:
- additional class in module (if it should be relocated, an example would be helpful, e.g. which mixins etc.)
- puts calls in the additional class
- exploit development and other comments welcome?
- Fedora ROP is on my TODO list (but I wanted to contribute the module before Christmas/holidays)
- Although I left "average ranking" in there, the exploit works for all targets with several tested (meterpreter, reverse_tcp, exec) payloads on the first execution run and is therefore very reliable.
Sorry, but no. I know now that would be the way to go, thanks for the hint and thanks that you take the time to read my stuff. But this improvement comes too late, I simply don't have the energy to test this again, especially as I feel if I don't this perfectly correct I could introduce the nasty raise conditions of the protocol again I had in the beginning (I fixed all of them by testing and tweaking the protocol on different OSes, architectures and so on). Of course feel free to change it if you like.
