Add -Credential parameter to pass PSCredential object

[trujello]

Would be nice to be able to pass in my PSCredential object that has the permissions needed rather than having to be logged in interactively as that user.

Sure it would be nice. Feel free to implement it. It requires a lot of changes and testing tho. I don't think I will have time to take care of it.

I will give it a go, @PrzemyslawKlys.

Great! Remember its easier to start one by one then doing all in one go. This way other people may chime in. Changing everytbing may take a lot of time.
