>0.89 compliant - "packaged" - 3rd pump integration - code cleanup - Hass.io ready (vs crc8)

What's different:

Home Assistant 0.89 and higher compliant
Hass.io ready (crc8 automatically installed when first used of this custom component on Hass.io)
Support 3 pumps
1 toggle operation for pumps *may be an issue at this point for some spa owners. jmoor3's spa seems to work with two, mine work with only one!
Code much more clean (no more allusion to "bullfrog", "Mitsubishi MQTT", "ecobee". Still a lot to do…)
