Add inventory mod

[warm bramble]

I would really like a mod where you can see your inventory next to your hotbar. This would be super useful for 1.9+ pvp, smp pvp, potpvp etc.
Basically you could just position a rectangle that when entering the game will show what you have in your inventory so you don't have to search for it while in inventory, as i said: super useful in pvp. It also would be nice to have it transparent, borderless, or customisable.
