fix+clarify ChunkTickScheduler, complete n.m.world.tick

[supersaiyansubtlety]

When adding a block tick scheduler to one of my mods I was dismayed to find ChunkTickScheduler had three fields that seemed very similar:

Queue<OrderedTick<T>> tickQueue;
List<Tick<T>> ticks;
Set<OrderedTick<?>> queuedTicks;

I was also surprised that void disable(long time) was the method responsible for making sure deserialized ticks actually get scheduled.

I've renamed them:

Queue<OrderedTick<T>> scheduledTicks;
List<Tick<T>> initialTicks;
Set<OrderedTick<?>> allTicks;
//...
void scheduleInitialTicks(long time)

I also added some javadocs clarifying how initialTicks works and renamed things to more consistently use "schedule".
