Added csproj and sln to final example

Unable to run final project without those files.

Thanks. Actually this apply not only to final project but to all the code provided for the different episodes.

None of them works directly without sln/csproj. You always have this type of error

E 0:00:01:210   can_instantiate: Cannot instantiate C# script because the associated class could not be found. Script: 'res://Scripting/Player/Player.cs'. Make sure the script exists and contains a class definition with a name that matches the filename of the script exactly (it's case-sensitive).
  <C++ Error>   Method/function failed. Returning: false
  <C++ Source>  modules/mono/csharp_script.cpp:2360 @ can_instantiate()

I am glad you provided this information as I was stuck

Edit: Actually I found a workaround to generate the sln & csproj files: Just create a dummy new c# script :)
