Breaking up flowers_plus mod (#5)

Splitting up flowers_plus into separate mods for seaweed, sunflowers and waterlillies, for clarity and so the user can disable them individually.
Fixed sunflower maximum heat.
Removed spawning, as we're already creating these things at worldgen.
Added settings for rarity and max count to each mod - waterlilies, seaweed and sunflowers
Removing along_shore mod as it does nothing now.
