Adding missing semicolon

Typo

Missing semicolon in line 2.
Replacing global declarations

Making global declarations to be locally. Hoisted the declaration of `AppDispatcher`, `TodoStore` and `callback` into the context of the main describe function, making them locally available for this context, instead of defining them as global variables.

Update "flux-chat", "flux-todomvc" and "TodoList.md" to React 0.12.0
Update examples to 0.12 and use object-assign

0.12 deprecates usage of merge and copyProperties and autofactories

Object.assign is provided in react/lib/Object.assign as of now, but may
move to a more freely accessible place in the future. Towards this
expectation, object-assign will be used in preparation.
