Black holes and deleting particles.

This update introduces Black holes, Deleting particles with the blopblopblop sounds and of course removed music from singleplayer because I forgot to add it back on, well at least it won't mix with the blopblopblop sound))). Anyways, black holes are just extremely massive particles that are larger than the normal ones and they're orange with black instead of pure white. Also they delete any particle that touches them (the player doesn't get deleted in sandbox). I decided to make the basics of an inventory. To spawn a bomb press 0, to spawn a black hole press 8 (or 9 if it didn't work). The right mouse button now deletes the selected particles.

Here you can see how much a black hole is bigger than a normal particle (sorry for it being so zoomed out).
