[9702] Drop now redundent item_text table.

* In beggining bad news: at 3.3.3 switch has been forgoted item_instance.data field chnage.
  In result items with texts (mail copy in to inventory, some other) lost text content.
* That why in current commit item_text droped without convertion. In result all itesm with texts
  will lost text. Sorry for this as i think small porblem :(
* Now text stored in item itself.
