Allow blocks in scripts

Ability to do stuff like placing blocks directly in scripts instead of using commands

Currently, it seems as though you need to use commands in your scripts to do stuff like placing blocks. It would be great if you could instead call a JavaScript function or fire an event that tells the game to place a block (or anything else that you need a command to do) rather than telling the game to run a command that does that thing because running commands seems to be a bit clunky to me.
