Could provide a passive boost to plant growth in an area around them. Not sure what the crafting recipe should be.

Tangentially related to #42

In addition to flowers, this could be a way to propagate and passively fertilize sweet berries. Maybe we could have our mason bees sometimes propagate melon and pumpkin seeds (if such plants are nearby) to grow wild crops, harvestable apples that grow on oak trees. When paired with the Spice of Life and its forks this could be a good way to passively farm a variety of vegan foods/ingredients.

Actually, this could be a roundabout way of implementing (part) of #42: native bee blocks could passively grow/spread flowers/tall grass a la Forestry, which could then be harvested and composted.

This could work, maybe the boost increases with flowers around the hive.

It could also have integration with Harvestcraft, Growthcraft, and Forestry, since they all have bees.

The recipe could be two logs, and five wood slabs.
