Create a BaseForm class which is the base of Form. Implications:
Create a BaseForm class which is the base of Form. Implications:

 * BaseForm allows WTForms's core behaviour to be used without requiring
   declarative subclassing of forms.
 * BaseForm implements the methods Form used to, plus a process() method
   to take input data.
 * Form is now essentially a declarative addon to BaseForm.
 * BaseForm allows for easier adding and removing of fields in forms since
   input processing is not tied to instantiation. Form retains its old behaviour.

All existing tests pass, existing tests forthcoming.
