• All of the unhandled errors related to inventory have been fixed.
  (Some nullchecks were missing where they should be)

For tomorrow's update, let's prepare for:

• Logging startup information into separate log file (plugins/ItemEssentials/warning.log)
• Adding "item-not-owned" and "lore-lines.bound-to" to translation options.
• Adding optional effect to items when used or not being able to be used, for example, when they cannot be picked up.

Thank you for bugs you have reported and helped me to fix them!
Have fun, and... Cheers!
