(Factions) Update the "Game Modifications" list for Factions

On the "Game Modifications" page in the forums. Under Blacklisted Mods ➼ Replay Mod (Only blacklisted on SMP) ➼ Free Cam (Only blacklisted on SMP) This implies that they are ALLOWED on Factions. This should be changed to clarify this. (World downloader is debatable, may go over that in a separate suggestion) Also, under Allowed Clients ➼ Lunar Client (Rewind mod is not blacklisted on SMP) this should also likely be updated.
