Improved vision on corps and activatable things

[WhatTheDuck]

Hi,

i'm new in the game and i think the best way to help you is to write whats my biggest problems are in the sight of a newb.

Sometimes i have a lot of struggle to find the corps after a fight or to see where are the enemys.
So i would recommend that you should expand the alt-key-function.

ATM it shows every item which is on the ground, it would be nice if it would also show every corp and activatable things like a well and also enemys, maybe just with a red or white borderline.

Greetings
