Add bare bones card creation

Mostly just getting a feel for the state update and re-render cycle.

The React tutorial has a form component that deletes the value of the
text box on submit. If the submission fails, this means your value is
lost. I implemented a less user hostile version that continuously saves
the value of the textbox to a "draft" area in the App's state object.
Add local db delete helper

While developing it is sometimes nice to start with a fresh DB. This,
intentionally, only destroys the local database, leaving it safe to use
in production, much like deleting your own copy of a source code repo.
Add points to card

I chose not to add fibonacci validation because we often make
place holder cards with strange amounts.
