Updated HomeSpawnUtils.isNewPlayer() to support 1.7.9

Updated HomeSpawnUtils.isNewPlayer() to support 1.7.9. This method breaks with the new player UUIDs and it not backwards compatible.

If it is possible to detect whether the server version is older than 1.7.9 then a backwards-compatible update and be pushed at a later date. I don't know how to do this and have asked the appropriate question on the bukkit forums.
