Inventory System more fixes

The game is right now playable. I started around 5-6 months ago with tuts on an
inventory system. Right now its the third version and i am using now a plugin base on the old tut.

Overall i am not satisfied. Its was stupid to put an complex system for an simple idea. Project management was not my strength.

An small idea endup in an complex game. Procedural gen maybe gets in.

There are some plugins like ProD etc. somehow its too complex and i dont know if i can get it working with my game.

I am planning to release an PC version too.

got working stacking for potions and working on the potions overall.
