Code: Tutorial for client signing of transaction - no steemconnect

[relativityboy]

Developers will want to be able to create transactions on a server, then send them to the client for signing, and ether pass them back through the application, or have the client post them directly to the blockchain.

Create a tutorial that follows both of these transaction paths.

AC

• app does not use steemconnect
• app points at testnet by default. Instructions on how to point to production (comment/uncomment line)
• use established best practices for this tutorial
• example runs server that generates low impact transactions at button click and sends to client
• user should be able to choose transaction type
• client signs transaction generated by server
• 1. client sends directly to blockchain
• 2. client sends to server which sends to blockchain
• success is indicated in UI.

Note
Creation of readme is covered in issue #8
