fix mod listener order

If the "MrTitaniumMap" modlistener runs before the "MoreRealisticDLCs", we get this error when starting a new game on WestbridgeHills :

Error: LUA running function 'loadMapFinished'
C:/Users/Labo01/Documents/My Games/FarmingSimulator2013/mods/MoreRealisticDLCs/_RES/map/MrTitaniumMap.lua(35) : attempt to index field 'dlcsData' (a nil value)
