[RELEASE] Z-Wave Firmware Updater

[Terk]

1. Change the driver to the firmware updater driver.
2. Ensure the switch is responding by clicking on Get Version Report.
3. Airgap the switch.
4. Put in the URL and click on Update Firmware
5. When it says to wake up the sleepy device, push in the airgap switch, let it go to the next step and then pull the airgap switch out again.
6. When it gets to the step where its waiting on the device again, push in the airgap switch and the firmware will start to upload.

I had to do these steps exactly this way on those 3 switches and they all finished the update.

I tried the 1st of my LZW30-SN On/Off switches and had to follow the above steps and be ready to push that air gap switch in quickly but it updated fine after that. Before it just kept nagging to wake up the sleepy device. Now just a dozen more or so to do. Thanks to @bcopeland for the excellent tool and thanks to @gavincampbell for figuring out the sequence to wake up those LZW30-SNs!
