Add context menu option to convert old style projects to new style projects
This can replace the current option to convert vulcan runtime to xsharp runtime.
Please note:
- Change references to the X# runtime to nuget package
- Change TargetFrameworkMoniker to TargetFramework
- Remove System references
- Remove items of type Compiler, NativeResource, VO Binaries, Managed resources, XAML etc.
- Keep project references
- Keep COM references
- Keep existing assembly references ?
