Poly Shooters update v0.43

I pushed this update release forward a bit because I noticed a bug that causes the game to crash under certain conditions when the level is changed at end of round. Here is what was changed:

- Fixed game crashing when level changed at end of round after timer is allowed to run out.

- Added red tint to screen when player is damaged.

- Added range and accuracy to weapons.

- Added player movement animations and weapon animations.

The animations are rough at the moment but I will refine them at some point, for now they are just a visual guide as to what's happening in-game.

I did not get to add new weapons this time around since I thought it would be better to get the bug fixed first so they shoud be in the next one.
