Fsharp example updated with the Demo version. (#407)
* Added solution file to the FSharpExample project. * Updated Terminal.Gui and FSharp.Core nuget packages * Removed the Terminal.Gui nuget package and added the project itself. * Added a new FrameView constructor with an array of views. * Changed FSharp Example with the Example Demo file version. * Fixes the Box10x() issue.
