(Separation is not perfect yet, because maybe there are some mayor changes needed :D)
- implemented CreativeInventoryAction (was mistakenly called CreateInventoryAction)
-> Fixed meta data for creative selected blocks
->->Slabs/Steps are now placed correctly
- slabs can now be build to a double slab
- fixed a bug in the inventory which put items with different meta values in the same slot
