Added forcekill command

This will help with players stuck in the wilderness. If they are skulled they will lose all their items (or all but 1 item if protecting item), if they are unskulled they will lose all items but 3 (or all but 4 items if protecting item).

This works well from my testing.

I'd also like to add some other commands in the future, only for administrators/developers, such as:

-Adding city names to ::tele command as possible args
-Adding item and NPC names to ::item and ::npc commands
-Adding ::itemsearch and ::npcsearch to show item and NPC IDs
-Adding ::spellbook swap command to quickly swap spellbooks

That's all I can think of off the top of my head but those might be nice to have.

Looks like the build error is not because of my code but rather the CI itself failing:

Error: This request has been automatically failed because it uses a deprecated version of actions/upload-artifact: v3.
