Void knight mace animations

What have you done in this MR?

• Re-saved item configs inside thanos editor to fix any manual editing inconsistencies
• (Unintentionally) fixed duplicate thieving cape req
• Added attack animations for void knight mace closes #814 (closed)

Are there any tricky things testers should keep an eye out for?

• No

• Yes, as follows:

• I have tested these changes thoroughly.

• This requires extra testing due to changes to architecture or other similarly risky changes.

• I used the Thanos Tool for any JSON edits where possible, and have attached screenshots of any changes.

• I acknowledge that this contribution will be released under the AGPL license.
