Salt crafting

[alek13]

Problem:

Difficult to mine salt. (for salads & bread and so on)

Proposal: (by Sakamoto in Discord) Proposal adjusted, follow things will be done:

• [x] bucket salt (bucket:bucket_salt) -> salt block (lottores:salt_block) (#1794)
• [x] bottle or glass with water (don't remember which one is filled from cauldron) -> salt 5 (lottores:salt)
