Onboarding

Detect if it's the 1st time the user is running the Light Wallet.

Case 1: The user has already used parity before

In this case he already has accounts on his parity, so can actually use the light wallet immediately after it's synced. We show the Syncing overlay.

Case 2: 1st-time user

We show the account creation steps, with the <Health /> component on the bottom to track the syncing progress. If the user finishes creating his account before the syncing finishes, then the Syncing overlay will show.

Ideas

• Show a small tutorial about what is the Light client? in both cases.

Anything to add/change @brianflanagan?
