Experimental Update 2/16/2015: Knockback everywhere and Hopping Hoppers... — Tom vs. The Armies of Hell Steam update #1042275

This update is kind of big (changes-wise) so it might be buggy. In light of that, I'm sticking to my original plan of updating the experimental branch first, so I don't break the normal one. First off, there's another tweak to ammo. This is purely a test, but curious how people feel. Now it will always give you ammo for your current gun unless you are full for that gun. Hopefully that's an improvement... we'll see. Aside from that, I've added knockback to pretty much all attacks (in small doses). I think it makes everything feel more impactful, but again, we'll see what everyone else thinks ;) I've also crushed a few annoying bugs. One was where the energy-weapon version of the laser rifle would stop cooling completely. Another was that Level 3 literally did not drop anything... that was... dumb. I think I fixed other stuff too, but I'm kind of sleep deprived and loopy right now, so what...
