FoodStats incompatible with Sponge

[squeek502]

See squeek502/SpiceOfLife#99 and https://github.com/SpongePowered/SpongeForge/issues/969 and https://github.com/SpongePowered/SpongeForge/issues/916

Sponge re-initializes FoodStats without the EntityPlayer field added by AppleCore, causing the player to be null unexpectedly.

• https://github.com/SpongePowered/SpongeCommon/blob/59ab9633ae5a7209dd385261df6843df825223a2/src/main/java/org/spongepowered/common/mixin/core/entity/player/MixinEntityPlayerMP.java#L489
• https://github.com/squeek502/AppleCore/blob/1.10.2/java/squeek/applecore/asm/reference/FoodStatsModifications.java#L15-L16

Not sure how to best resolve this yet.

Some possible fixes:

• Set the player if it's null every FoodStats.onUpdate. This would basically be a band-aid, and would still fail before the first onUpdate call, but it might work to help resolve issues like this in the future
• ASM into the modified Sponge code and insert the EntityPlayer into the FoodStats constructor.

Should be fixed with https://github.com/SpongePowered/SpongeCommon/commit/384180f372fa233bcfc110a7385f43df2a85ef76.
