BukkitClasses - reformat Block's toString to include more helpful info

[ShaneBeee]

Description

This PR aims to reformat a block's toString() method, to include more info.
See #3315 for the discussion.

I know it was up in the air whether or not a world should be included, and its potential to be too verbose, I included it, as users may have block stored in variables, and this just prints a more accurate accounting of the block.

Ex code:

on load:
	set {_b} to block at location(-910, 12, -234, world "world")
	send "Block: %{_b}%" to console

Output:

Block: 'raw andesite' at -909.5, 12.5, -233.5 in world 'world'

watch out for the performance of this method, String#format can in fact be quite expensive in some cases, I imagine users won't do it often enough that it'd become an issue though
