Update to call TransformXml directly from PowerShell instead of going
thru msbuild.exe.
Because of this on the second+ publish the assembly is locked in the Out

folder but from a different location.
Completing updates to support multiple transforms.
When prompted for transforms you can now pass in multiple transforms by
seperating them with a ; character. The transforms will be executed in
order from left to right.
