Host Information Enumeration via NTLM Authentication

This aux module makes requests to resources on the target server in
an attempt to find resources which permit NTLM authentication. For
resources which permit NTLM authentication a blank NTLM type 1 message
is sent to enumerate a a type 2 message from the target server. The type
2 message is then parsed for information such as the Active Directory
domain and NetBIOS name.

The user can provide their own TARGETURIS file which contains URIs
to request to attempt to get a 401 with NTLM. This PR also includes
a list of URLs that can be used as the default.
