Hidden Hydration

This quality-of-life mod simply expands the area where a water block may be in order to hydrate (water) a farmland block. It adds an additional, 3x1x3 layer _below_ the crop block where water may reside. This makes it possible to create "fields" where water is hidden under the block. More specifically, it changes the water _scan_ area. Assuming (0, 0, 0) is the position of the farmland block, the scan ranges from: ``` vanilla: (-4, 0, -4) to (4, 1, 4) mod: (-4, 0, -4) to (4, 1, 4) + (-2, -1, -2) to (2, -1, 2) ```
