Small Hydroponics update.

Added Rice and Plastellium plants. Rice stalks are grinded into rice that you can make boiled rice, rice pudding and Sake from. Plastellium is refined into plastic by grinding it into plasticide. 20 plasticide + 10 poly acid makes 10 sheets of plastic, which can be used to make plastic crates, plastic forks, plastic spoons, plastic knives, plastic ashtrays or plastic bags from.
