[NSE] Script Submission: NoMachine Version Enumeration

[nmap user <nmapuser1 () gmail com>]

Hello,

NoMachine is a popular cross-platform remote desktop solution. Attached is
a NSE implementation to fingerprint/enumerate version details from a
NoMachine Network Server.  By sending a crafted packet declaring the client
version, the server will respond with the version of nxd.

Example Output:
#nmap -sV -p4000 --script nomachine-info 1.2.3.4

Nmap scan report for 1.2.3.4
Host is up (0.0035s latency).
PORT     STATE SERVICE   VERSION
4000/tcp open  nomachine NoMachine Network Server (nxd)
| nomachine-info:
|_  Version: NXD-5.1.26

Thanks,
-J
