david 8bd71aaf43 Normalize NSEDoc documentation of scripts.
I made every script follow a standard form: it starts with the id, followed by
the description. The description is contained in [[ ]] delimiters. The
description is in the global description variable, not in a LuaDoc comment.
Other LuaDoc information such as @args and @usage follows the description in a
comment.

The first paragraph of each description is a a short summary of what the script
does. More detailed information, if any, is given in following paragraphs.

I also improved some wording and formatting in a few cases.

id = "MSRPC: List of domains"
description = [[
Attempts to enumerate domains on a system, along with their policies. This will
likely only work without credentials against Windows 2000.
\n\n
After the initial bind() to SAMR, the sequence of calls is:\n
Connect4() -- get a connect_handle\n
EnumDomains() -- get a list of the domains (stop here if you just want the names)\n
QueryDomain() -- get the sid for the domain\n
OpenDomain() -- get a handle for each domain\n
QueryDomainInfo2() -- get the domain information\n
]]
