Feature Request: Support for entering hidden passwords on the command line

[GoogleCodeExporter]

Hi.

Thank you for NConsoler 2.0.

I am using Windows 7 Ultimate x64 SP1.

I'd like to request the ability to specify a required parameter to the target 
function that should be entered on the command line so that the input is hidden.

This is specifically and especially useful when entering in a password on the 
command line.

For example,
[Action]
public static void DoWork(
[Required(Description="username")]
string username,
[Required(Description="password", Secret=true, Prompt="Enter password", 
Masked=false)]
string password)
{
  //implementation
}

And then on the console, the prompt for the password would appear as follows, 
where the entered password is not displayed:

>CommandLine.exe rami
Enter password:


Notice that an additional feature (but lower priority IMHO) would be to 
actually mask the input.  I explicitly set this to false because I don't want 
others to know how many characters my password is, for example.  I'm not 
exactly sure if it would be useful for other things though.  Maybe the Prompt 
attribute parameter could be optional, so that it will display "Enter password" 
if the Description parameter is specified as "password" for example.  But it is 
there to support entering in multiple passwords on the command line for example.

If users want to actually specify the password in an unattended scenario, I 
would also imagine the ability to pass the password to the command line 
application.  In my experience, I've been able to pipe a password to a command 
line application before, but haven't tried piping multiple parameters for 
example.  In this case, it may be best to support hidden inputs by explicitly 
using the OptionalAttribute with an optional "Required=true" attribute 
parameter for example, instead of the RequiredAttribute, or support both 
scenarios, but that may be a little too complex, and so may be left for a 
future version.

Thank you very much.
