Added new custom spawner names for Premim users :

• - You can now set custom names and and lore for spawners
• - Color codes supported! E.g.:

zombie:
name: "&cA Scary Zombie Spawner "
lore:
- "&7This spawner will spawn &czombies&7"

Added support for ShopGUI+ ⚠️ Experimental ⚠️:
The code to make it work was implemented, but I can't confirm it works
until I get confirmation from the community.

I couldn't test it myself because I don't own a copy of the plugin, and the owner did not want to provide a trial version of their plugin.
