This adds retains support to published messages. It should be backwards compatible with existing clients as it defaults to false if not supplied. Solves #20 and #161
Added an optional flag on publish to set the retain flag. If set to true the MQTT broker will retain the last published data. As the flag is optional it...

One useful pattern to track device up/down status is to have a will set to .../status with value '0' and retain, and when the device comes up to publish to...
- **Describe the scope of your change--i.e. what the change does and what parts of the code were modified.** This will help us understand any risks of integrating the code....
