Subject: Humidity for melons.

Lots of more templated code here. Use swap_node throughout. Each
plant has it's own properties table now, which trims the settings.txt
file. Will be easier to maintain and extend.

Had to add a withered texture for the melon plant... yes melon
plants will be able to wither on hard settings.
