Refactors HWNDView, NativeViewHostGtk and NativeViewHost so that they match the NativeControl pattern established for NativeButtons. NativeViewHost is a platform-neutral class that clients instantiate. Behind the scenes the platform instantiates the appropriate NativeViewHostWrapper implementation, either NativeViewHostGtk (as before) or NativeViewHostWin (replaces HWNDView).
