* Optimize I/O access A single update() will now fetch information from all interesting modules, including the current device state and the emeter information. In practice, this will allow dropping the number of I/O reqs per homeassistant update cycle to 1, which is paramount at least for bulbs which are very picky about sequential accesses. This can be further extend to other modules/methods, if needed. Currently fetched data: * sysinfo * realtime, today's and this months emeter stats New properties: * emeter_realtime: return the most recent emeter information, update()-version of get_emeter_realtime() * emeter_today: returning today's energy consumption * emeter_this_month: same for this month Other changes: * Accessing @requires_update properties will cause SmartDeviceException if the device has not ever been update()d * Fix __repr__ for devices that haven't been updated * Smartbulb uses now the state data from get_sysinfo instead of separately querying the bulb service * SmartStrip's state_information no longer lists onsince for separate plugs * The above mentioned properties are now printed out by cli * Simplify is_on handling for bulbs * remove implicit updates, return device responses for actions, update README.md instructions. fixes #61
