More grunt work on the GUI...i really hate making GUIs and/or GUI frameworks. I somehow always feel dirty afterwards...anyway, it now has the inventory, a quickslot bar (right to the inventory), the player's silhouette to equip items and a text area with item descriptions. Draging, stacking and splitting seems to work fine now between all components, but the code that handles this looks like s**t...
Anyway...
Edit: Nothing in this prototype is final btw...it's just a kind of reusable test case (which means that most of the stuff should be usable in the actual game).
