[NSE] Call for testers: skypev2-version improvement

[Daniel Miller <bonsaiviking () gmail com>]

List,

I've just finished working on some NSE improvements using cached service
probe responses to avoid sending additional probes during script scanning.
You can see this in action in the http-server-header script as of r33712.

I have produced a similar improvement for skypev2-version which ought to
avoid 1 or 2 requests per open-but-unknown TCP port. Additionally, it uses
formulas.looksRandom instead of a cryptic Lua pattern to determine
"randomness" of the response.

Unfortunately, I don't have a Skype node here to test on. All I need is for
someone to run the attached script like so:

nmap -sV -d -p 80,443 some-skype-server.ip

And then report that it correctly identifies those ports as skype2. If you
want to further add --script-trace and confirm that the script sends no
packets itself, that would be fine. I've already tested against a
non-skype-but-unknown service and things work fine.

Thanks!
Dan
