Register file name extensions for side-by-side deployments

For VSPackages deployed in a side-by-side environment, you must register file name extensions to associate the files with the correct version of Visual Studio. Unless you use a version-specific file name extension, registration enables users to open your project and project item files in the appropriate version of Visual Studio.
