subspace tripmine

this adds the subspace tripmine from roblox plus a few other things. when placed, after about 5 seconds, the block will go invisible, and any player/entity that touches the tripmine will cuase it to explode. creating a large crater surrounded by a purple residue (you can see this in the images tab) which can be used to craft more tripmines

in order to craft a tripmine, you must first craft a subspace star, which can be done in 2 ways:

method one (this is what you use to make your first bomb) is to surround a nether star with ender eyes like this:

method 2 is to surround an ender eye with the purple residue like this:

to craft the tripmine itself, you just surround the star with 4 iron bars and 4 iron blocks like this:

the purple stuff is also a bit sticky which causes you to walk a bit slower and jump lower. which could be useful for something
