Bug

We should edit the 'parms' variable in the script and change
'+servercfgfile' to '+exec', like this:
parms="-game csgo -usercon -strictportbind -ip ${ip} -port ${port}
+clientport ${clientport} +tv_port ${sourcetvport} -tickrate ${tickrate}
+map ${defaultmap} +exec ${servercfg} -maxplayers_override ${maxplayers}
+mapgroup ${mapgroup} +game_mode ${gamemode} +game_type ${gametype}
+host_workshop_collection ${ws_collection_id} +workshop_start_map
${ws_start_map} -authkey ${authkey}"
