And refactor the artifact staging a bit.

@weshaggard I've removed a bunch of New-Item invocations in favor of a Copy-Item with -Force parameter. If we know we're copying into a clean directory, do you see any downsides to this approach?

Does copy-item -force also create directories?

Does copy-item -force also create directories?

Based on a quick test it doesn't appear to so you still need to new-items to create the directories.

@weshaggard I completed some local testing. I'm fairly confident that my approach for New-Item will be safe. I've got everything the way I want it except for the publish to nuget (which got commented). I'll uncomment, squash, and checkin when I have the successful release.
