Better melee and new melee weapons — EMPTY SHELL: PROLOGUE Steam update #75200

Now voluteers can spawn with 3 new melee weapons: a shovel, a crowbar and a hammer. All the melee weapons now have a proper range of action and stopping power (for example, the hammer has the shorter range and almost no stopping power, the shovel has the larger range and decent stopping power). The final boss has now higher health and mass (that means lower knockback).
