Subject: [PATCH] Prevent Waterflow BlockFromToEvent from loading chunks
Many protection plugins would unintentionally trigger chunk loads
by calling .getToBlock() on an unloaded chunk, killing performance.
Simply skip the event call. as CraftBukkit blocks changing the block
of unloaded chunks anyways.
This keeps behavior consistent, vs inconsistent flowing based on plugin triggered loads.
