Workshop for handsome adventurer

temporary solution for the mess with Backpacked mod:
* version 3 of backpacked mod fully supported.
* version 2 of backpacked mod partially supported: backpack on-back not accessible from my crafting tables; place a shelf close to the crafting table (can be one block above the table base), then put the backpack onto its shelf to have its content accessible from the table gui. when done crafting pick up the backpack from the shelf and off you go.
