Farm form

I added two class based forms with views

Forms:
NewFarmForm & EditFarmForm.
Views:
NewFarm & EditFarm

I took out the following views
newFarm & editFarm

I also added four tests to test each new form and view.

The NewFarmForm has a feature where it adds the memberorganization of the person creating the farm to the farm apon creation.  Theresa may want that changed for Salvation farms administrators.
