Makes a number of changes to the GUI (removes a few hardly used icons and adds an exp counter).

In multiplayer coop you will get the number of earned XP instead of deaths.

On the endgame screen you will get Kills, Deaths and XP

On endgame screen I activated the timeline (haven't got a clue what it is good for ;)

Did remove the icons for drink mana/health (didn't use them a single time)

Removed the useless semitransparent bar at the bottom of the screen (really makes the world look bigger)

Added credits information on the start screen ;)
