Inventory+2

Hello kids!

I spent my Sunday afternoon with inventory programming and the result is: Inventory+2 ZX, now with advanced features like:

• choose the amount of the items you want to drag & drop,
• ...,
• well that's it, but that feature is complex, believe me!

For the trading it's convenient to make stackable item handling into something cool. If it's not good, you can't sell 3 out of 5 gems at the trading station and that would be shame. No one wants that (well, a couple guys want to sell only 2 gems out of 5). Fortunately the feature is just finished! Yay!

There is only one thing left from the trading: create the trading GUI!
