Update 0.126 - The last one, for now

This is the final build of Zone Zero that will have the surviv.io style.

The producers are doing a full overhaul of the game's aesthetic and gameplay. We are not going to be redoing code, but almost everything design related is going to be changed: The game's art, setting, enemies, player movement, inventory, and style.

In this update, the Hud has been updated, enemy AI has been tweaked, the RB12 shotgun is added, and aiming will now slow down the player's movement.
