Scripting: FindEntityWithName and get script instance

+ Some C# UUID stuff
+ Added some Mono functions
+ ScriptEngine:
  + ID -> ScriptInstance map in ScriptEngine
  + GetManagedInstance

+ Fixed Scene not visible after loading a new scene
  + Renamed OnViewportResize to SetViewportSize for Scene and SceneRenderer
