NAnt Vault Tasks Updated

Jonathan Cogley asked and posted about needing an update to the NAnt Vault tasks. I can't say everything is perfect, but I have updated the code so it will compile. I don't have everything I need to fully test the changes (primarily updates to NAnt 0.8.4 and Vault 2.0), plus I had to remove the Label task since it isn't obvious how to do that with the new vault APIs.

If you haven't already checked it out and you are using Vault and NAnt take a look.
