Vastly extended hologram configuration

- You can now completely customize every part of the hologram
- Added new placeholders "%STOCK%" and "%MAX-STACK%"
  => Now uses "%STOCK%" instead of "%AMOUNT%" in the in-stock message)
- Armor Stands are no longer spawned with NMS and reflection
- Hologram texts can dynamically change (e.g. with in-stock info)
- Might contain a few issues
