Add `unified_inventory_enable_item_names` setting (#235)

Show only names settings: in case of multi-line descriptions, only the first line is shown
Shorten long descriptions: Removes all characters after x index, and add `[...]`
Max length before truncation: x for Shorten long descriptions
Notes: If Max length == 0, then item names won't be displayed
