First-run wallet creatorator (v0.7.0) (#24)

Adds a first-run wallet and account creator option for noobs.
If they select the "create a default wallet" option, they are jumped to the name + password screen for wallet creation, and a new account is generated for them named "Account 1".

This leapfrogs the problem of users having to know what is going on with the blockchain and wallet at all before getting started.
