…captures

state that state is stale. This is the case because we never change the render
function - even tho it's instantiated.

This change makes it possible to access outer state and re-render when captured
state changes.

This is still a prototype.

… requires not using an FSharp

function as getting the address of a function type is prevented by the compiler. I guess casting the
function to an object might have also worked here.

- simplify bindings by passing in the RenderFunctionProperty

… functions. This works but is

still a bit messy.

Component: plain old component, unchanged from master

ClosureComponent: component that works well with render function that captures state
