Recent improvements to my NuGet packages

I've improved my NuGet packages for sharing feature files and constraining test-generation.

As of 2020.4.2.5, the following changes have been made:

• Feature files are imported to a hidden folder under your base intermediate objects path (usually obj\). This helps make it more clear that the imported feature files are build-artifacts, not maintainable source code.
• Control tags for other test libraries can be stripped out of the test-generation process. This will help prevent miscategorization.
• Shared scenario templates/outlines which were being broken by the incredibly-offensive importance of this class now work properly.

Fun.
