Watermelons

So, what's this, then? Quite simply, it adds square watermelons. You can place them, plant them, grow them, eat them...

It all starts with a simple vine...

Which grows, and grows, and grows...

Until finally...

Watermelons! Nom! These vines also sprout up randomly during world generation, on the ground near bodies of water.

Once you've discovered one of these scrumptious, succulent fruits, you can "break" one to pick it. Chopping down the vines has a chance of yielding some seeds, which can be planted to spawn MOAR MELONPLANTS.

As for the melons themselves, they can be placed and eaten (up to five uses, each healing 1.5 hearts)

Or, if you prefer, you can cut each melon into four slices, which are stackable up to sixteen and can be eaten from your inventory like any other food, healing 1.5 hearts. The reverse can also be done.

''Side note: if you eat a watermelon block once it's been placed, the drops change for each use. (Full watermelon = drops itself, one bite = three slices, two bites = two slices, three bites = one slice, anything else doesn't drop.) Also, you can slice watermelons into 4 slices by breaking it with an axe.''

And that's about it, I believe.

Oh, yes, watermelons can only be placed/stay placed when there's an adjacent block on any side. In other words, no unconnected floaters.
