Version 0.16

Hello again :)

We have a couple of changes, one of them being rather major while the others are just small tweeks. Here they are:

1. Particles will no longer heavily influence the atom's movement, allowing it to collide with them without the fear of bouncing away or slowing down.

2. Fixed some bugs revolving around the atom not changing it's mass or gravity scale when switching between different states.

Next is to add some more sounds!
