Addin project templates target .NET 4.5.2

[agc93]

Creating a new addin project using the project template creates a project targeting .NET 4.5.2 (resulting in a NuGet package using lib/net452) which is not supported by Cake.

These projects should target .NET 4.5 (net45) instead.

So there's no way to control this from the extension as it's all decided by the New Project dialog.

May need to add a note to the documentation if this comes up more.
