Full local storage through object serialization

New in this release:

• Typescript serialization via implementing fromJSON and toJSON methods (see http://choly.ca/post/typescript-json/)
• Full board state is saved along with game counters, so you can resume a game previously saved.

Basic game setup

Basic rules as they were created in the original plain Javascript game:

• Simple BlackJack rules (as the Spanish "21" game).
• Discrete layout with card sprite.
• Save and reset using browser local storage.

New in this release (to the old version)

• React components
• Typescript
• Jest tests
