Changes

Melded the API of foreign-var 0.1 with the API of StateVar 1.0.1.1
Introduced HasUpdate, which permits a wider array of uses of these combinators, including usecases that must update atomically.
Switched to multi-parameter typeclasses. This permits Ptr a to be directly employed as an instance of HasGetter, HasUpdate, and HasSetter.

Exposed GettableStateVar, SettableStateVar and StateVar constructors to make writing own instances possible.
Added Functor, Applicative and Monad instances for GettableStateVar.
Various infrastructure improvements.
