Fix starvation on world entry.

The player would starve on world entry under specific circumstances.
To reproduce, load a world older than TFC_Time.startTime after
restarting Minecraft completely.
The players food stats were being loaded before the world time, thus
resetting the player timers.
I may be wrong but  I think this is a symptom of some other deeper
issue, I tried to find a place to update the worlds time before anything
calls getTotalTicks() but I could not find a solution. Hopefully someone
with more knowledge about this code base will find this useful.
