Compatible economic plugin CoinsEngine

[virgil698]

Describe the feature

CoinsEngine is an emerging multi-economy plugin system. Its ease of use is being adopted by more servers as their economic system. We hope that the CrazyAuctions plugin can be integrated into this system to enable it to function properly with its economic components. Thank you for the developers' assistance.
