Combined hoe fixes

[Sefiraat]

Description

Combined hoes have not been working as intended. Couldn't till grass. Seeds added aren't saved and broken plants wouldn't trigger the 3x3 area.

Changes

Added EquimentSlot field for updateHeldItemStack. Added updateHeldItemStack to GuiClose and PlantSeeds saving the seed type and amount correctly. Changed material check to GRASS_BLOCK. Set seed bag to Right click air only, otherwise it opens when planting seed and is generally more convenient to separate the actions, updated lore to suit. Protection check was incorrectly inverted and would only break protected blocks. Reversed.
