Fix minigun not pausing the turn timer properly

#!/bin/sh -
# === HWMAP-to-Lua converter ===
# This script allows you to put arbitrary HWMAPs into your missions!
#
# Usage:
# It expects a .hwmap file of name "map.hwmap" to be in
# its directory and creates a Lua file (map.lua) containing code to
# draw the map.
# In Lua, call drawMap() in onGameInit. And don't forget
# to set MapGen to mgDrawn. Then your map should be ready to go! :-)

# FILE NAMES 
IN="./map.hwmap";
OUT="./map.lua";

# TEMPORARY FILES
TEMP_UNBASE=$(mktemp);
TEMP_GZIP=$(mktemp);
TEMP_OCTETS=$(mktemp);
