Package cloning

This release adds:

• The ability to clone the latest packages from the source server to the destination server.
• If a package has build information associated with it, that is also uploaded.
• The CloneSpaceProject script will find the package(s) for each step and add them to the list to get cloned.

Please note: This is using a very simple download mechanism, it isn't the fastest in the world. Bigger packages will slow down runtimes. You can exclude packages by setting PackagesToClone to $null or excluding it altogether.

Bugs fixed:

• Downloading files now work when running the script on Linux / MacOS. The code uses System.IO.Path.Combine instead of hardcoding the forward or backslash.
