Added most plant growth modifications (see TODO.md)
 * Only the vanilla block modifications will work for now, as AppleCore doesn't hook into the modded plant blocks yet
Various fixes
 * Reverted the _at foodLevel/foodSaturationLevel changes
 * Uncommented some Module init calls in HungerOverhaul.java, because them being commented is too abstracted from the actual code that needs to be fixed (the module needs the changes, not the init() calls)
