Add /copyval

[ashlikatt]

Overview:

Adds a command (/copyval) which will convert the held Code Value into a string and copy it, if possible.
Configuration exists for the command to change the format of the string copied using Java's format syntax.

Intended Use:

This command is intended to be used by players using external DF programming languages. It provides a relatively convenient method to convert common code values into a custom string format to be pasted into a script.

Available Settings:

Note:

It is definitely possible to add some more advanced configuration, like some type of regex replacement rules or something, though that feels very overkill for this.

Files Changed:

• CommandHandler.java - Registers CopyValueCommand
• CopyValueCommand.kt - Holds logic for the command, bulk of the code
• CommandsGroup.java - Adds a new group and settings related to the command
• ValueItemUtils.kt - Helper file to add ItemStack#getDFValueItemData() for CopyValueCommand.
• en_us.json - Descriptions and names for settings
