Add proper support for GHC 7.0+.

Rather greatly widened the range of GHC versions we can support.

Avoided using 'type' in the export list, as that doesn't work on 7.4.
ProfunctorAdjunctionbecause GHC 7.4 still exists in the wild.
:->for the same reason. Also the former was confusing as they conflated profunctor homomorphisms and profunctors themselves.
- Flipped the order of 'Procompose'
- Added the notion of Monads and Comonads on the category of profunctors.
- Added 'Cayley' which takes normal Haskell Monads and Comonads to a 'ProfunctorMonad' and 'ProfunctorComonad' respectively. Cayley is also known as the 'static arrow' construction
- Added 'Closed' which is adjoint to 'Strong'.
- Added 'Closure' which freely adjoins 'Closed' to any 'Profunctor'.
- Added 'Tambara' which freely adjoins 'Strong' to any 'Profunctor'.
- Added 'Cotambara' which freely adjoins 'Choice' to any 'Profunctor'.
- Under the new 'Procompose' the old 'Rift' is now 'Ran', and the old 'Lift' was misnamed. It is now 'Rift'
