Load dummy data into localStorage for namesList

To make a more complete example of usin Flux to CRUD a resource, I'm
adding the 'namesList' for CRUDing favorite names.

The first step is to mock up a dummy server using localStorage. Names
will be under their id in an object under the localStorage key
'namesList'.
Add server actions and API utils for mocking CRUD of names

To use flex for a more full CRUD of a resource, I'm creating a
'namesList' for saving favorite names. This commit adds API helpers to
persist creating and deleting names on a mock server (localStorage) and
a set of server actions to serve as callbacks for successful persistence
to the server.
Namespace the constants

We are using a set of global constants to hold the keywords used for
CRUD events. This is a good thing, because with the introduction of a
new resource it won't do to say 'create' without any mention of what is
being created. This commit namespaces the constants and puts them in
sync with the new server actions.
