Changed the color from black to dark gray for coal when viewing the item sack as an item or in the GUI for better readability.
Sacks can now pick up quartz, ancient debris, and netherrack.
Added /miningsack command for viewing the current plugin version.
The new changes give a different look for the sack lore. To update current sacks on your server to the newer version, you will need to open the sack once. You will not lose any of its contents.
