hostmap.nse improved! Added new "ip to hosts" service provider

[Paulino Calderon <paulino () calderonpale com>]

Hey everyone,

    This week the GSoC NSE team had a meeting where we discussed how 
Bing and the search keywords "ip:<ip>" return additional hostnames that 
hostmap's current service provider, 
http://www.bfk.de/bfk_dnslogger.html, do not.

Long story short, I wrote http://www.whataremyhosts.com, an 'ip to 
hosts' service provider that uses Bing results and I added support to it 
in hostmap.nse.

The new argument 'hostmap.provider' may take the identifier of one of 
the providers (BFK or BING) or it will use both databases to create the 
list of hostnames.

Usage examples:
* nmap --script hostmap --script-args 'hostmap.provider=BING' 
calderonpale.com <-Only bing
* nmap --script hostmap --script-args 'hostmap.provider=BFK' 
calderonpale.com <-Only BFK
* nmap --script hostmap calderonpale.com <- Uses both databases and 
merges results by default.

Cheers.
