Add random.seed() in x_forwarded_for constructor and use threading2 branch

Think this is still not working right but I don't know way.
I did two times the same scan and saved the X-Forwarded-For header with
grep X-forwarded-for output-http.txt > /tmp/scan1/2
http://pastebin.com/rfXktADV  => scan 1
http://pastebin.com/dVK17yEt  => scan 2
Maybe I shouldn't use random at all and just do it with a counter variable?
Like:
87.87.87.1
87.87.87.2
87.87.87.3
87.87.87.4
...


Discovery Plugin (X-Forwarded-For: 127.0.0.1):
Yea this is a good idea I can do this in the feature.

PS: You are NOT annoying ;-)
