Implement optional direction vector to activateItem

[Sheepy3]

implements optional vector parameter into activateItem, as per issue #3621. allows for providing direction vector when bot is performing actions like throwing potions.

Please fix the linting errors. Otherwise this looks great, I've been looking forward to this feature for a while so i can automatically mend the bot's armor when durability is low.

Tests don't seem to pass, might be unrelated as I don't see how this PR changes could cause this.

Error seems to be:
