VAB: Allow users to tell which part is already attached to the craft.

[Dunbaratu]

The artwork for many parts is very similar, making it hard to tell which part is attached to the ship, and right now there's no way to tell. I propose either a tooltip popup with the part name when your mouse hovers over a part in the VAB that's ON your craft, or highlighting the relevant button over in the parts bin panel on the left when you hover the mouse over the part on the craft.

Thus you can better tell if the part on the ship is THIS solar panel pack, or THAT one.. or if you have THIS engine or THAT one, etc.

It's easy to claim that you should know what parts you put on the ship yourself, but if you save the game and come back to the design later, it could have been many days since you attached the part - plenty of time to forget.

I think the tooltip idea would be the most practical. Most easy to use and implement. But it should only be active, when you are not holding any part with your cursor. What data it should display i am not sure: Maybe just the name, maybe more... But the name of the part would definetely be helpful at times.
