Example Renderer, Broker and message creation applications

## Problem

I was so eager to get a simple application built to demonstrate the Broker *pattern*, I neglected to actually use the Alephant (broker or renderer) gems at all.

## Solution

Keep the existing example code I put together previously as an example of the pattern (e.g. `Example/Without-Alephant`) and copy the example and modify it to use both Alephant-Renderer and Alephant-Broker (e.g. `Example/With-Alephant`)
@revett yeah good call on naming the app `Sender` rather than just `App`.
