Adjust item types that allay can pickup when renaming the item

A convenient way to adjust the range of items the Allay can pick up is by setting a "code" that would read the name of the item the Allay is carrying. Such code could be to use a special character (such as "§" with texts) and a number or keyword depending on whether you want the Allay to pick up similar items, the specific item, or to distinguish between enchantments.

An example would be having a diamond sword with sharpness II and having the following options:

1) Rename the sword to "#1" and the Allay will pick up only diamond swords with sharpness II.

2) Rename the sword to "#2" and the Allay will pick up only diamond swords.

3) Rename the sword to "#3" and the Allay will pick up swords of any material.
