You can now combine multiple placeholders together, and run multiple operations on a single placeholder!

Before, you could only use one placeholder at a time, like {location.x + 5}

but now, you can nest placeholders and do things like {location.x + {location.y + {location.z}}}, or {{location.x / 2} round 0}

The wiki https://github.com/jojodmo/CustomItems/wiki/Handlers-and-Actions#message-and-command-placeholders will be updated with more information about enhanced placeholders soon!
