Added functionality for MSdeploy

Hi,

I have added some functionality to be able to do an MSDeploy from albacore. This is mainly focused around the deployment of a package to a server and not some of the more advanced features for cloning and synchronising servers.

This is my first git pull request so let me know if I have made any errors in the process. (I think I have but cannot figure out how to revert them) as i have
 - bumped the version to 0.2.8
- removed the albacore.gemspec file (Which was generated at any rate so not sure if this is OK)

I have also fixed issue #188 as this was causing an issue using nuget in our environment.
