Show Info when in inventory

[Aryezz]

I can see why this would be a debatable feature, but since the Debug screen is also visible when in inventory i think that it makes sense to show the info as well

The debug screen is what the name implies, filled with debug information. IGI on the other hand is supposed to be an HUD mod.

I'll see if this can be done in a simple way without tearing up too much stuff.
