REACH-123 Add view for String node

Send correct value of a String node to Flood
Thanks @marimano, this looks good. If I may suggest a small change, here's what I'd like to see:

```csharp
switch(GetCreationName(node))
{
    case "Boolean":
        break;
    case "String":
        break;
    default:
        // Bla bla bla...
}
```
