Dried Plants, Coffee, Tea, and "Roll your Own" supplies.

This adds new plants:
Tobacco -> Space Tobacco
Coffee Arabica -> Coffee Robusta
Tea Aspera -> Tea Astra

A Drying Rack has been added as well. You can craft it out of wooden planks. 
It is used to dry out most every grown plant, as well as meat into jerky, and grapes into 4noraisins.

Dried Coffee beans and dried tea leaves may be ground to make coffee or tea powder respectively.
Coffee and Tea powder reacts with water to make coffee or tea.

Added to the Cigarette vending machines are packs of rolling papers.
These packs hold 25 rolling papers each.
Rolling papers can be used on any dried plant in order to create a "rollie" which will contain the source plant's reagents, and works like a cigarette.

The rollie's description will tell you what it contains.

I am open to more suggestions on more uses for the drying rack.

Iamgoofball added mechanics for the existing pipes so they use dried items now.
He has also added the ability to wrap a tower-cap log in certain dried plants to make a torch.
