Better C++/CLI support

Since the ReSharper license now covers both ReSharper and ReSharper C++ products, support for C++/CLI – a bridge between the languages – is getting a lot of updates and improved interoperation between C++/CLI and C#.

ReSharper C++ will find derived symbols in C# code, while Go to Base Symbols and Go to Derived Symbols now work on imported CLR entities.
