Multiple transformer versions located in packages folder

[tobiaszuercher]

sometimes nuget fails deleting it properly :( so sad!

options

• let's add a warning to the console which tells the user to delete the old version.
• warn user in console and ask directly to delete the old version
• delete the old version
• just load the newest version + warning that there were multiple versions

i solved this issue by placing a packages.config in the folder where the nuspec lives and manage the version of the transformer there, independently from the version used in the Visual Studio solution

The build-step contains an additional nuget restore for that single NuGet-Package
