Describe the bug

• Manually waterlogging the Plinth with a bucket does not work
• To fix, block class is missing the implements IWaterLoggable after the class name.
• It would also be cool to see waterlogging added to all the other blocks. It could provide for some good decorating opportunities.

To Reproduce

1. Place plinth
2. Right-click with a water bucket.

Environment

• Eidolon v0.2.1
