Upgrading player gui redux

ref #6518
I am sorry, I was not aware that source artwork was available in repository, modifying it is only right way to do changes

Please be not affraid of modified *.psd, i was not replacing original logo layers, if that would be needed in future
I am also very particular to pixel level, so there shouldnt be any negligence

final result:

You should add the `powerIcon` expression as its own definition here instead of mixing it with `power.GetColor`:

```csharp
powerIcon.GetImageName = () => powerManager.ExcessPower < 0 ? "power-critical" : "power-normal";
power.GetColor = () => powerManager.ExcessPower < 0 ? Color.Red : Color.White;
```
