* Add support for new-style emeter
This commit adds a straightforward dict-extending container,
which converts between the old and new keys of the get_emeter_realtime()
Furthermore the unit tests are converted to base on HS100
instead of HS110.
This is the first step to fix#103, other emeter-using functionality
has not yet been converted, only getting the current consumption.
* fix a couple of linting issues
* Convert new-style emeter values also for get_emeter_daily() and get_emeter_monthly()
* Adds a new 'kwh' parameter for those calls, which defaults to True
* This changes the behavior of bulbs emeter reporting, use False if you prefer the preciser values
* move has_emeter implementation from SmartDevice to SmartPlug, avoid using features() internally
* add stacklevel to deprecation warnings to see where they are really called
* make tests pass on a real device. if PLUG_IP is not None, the tests will be run on a device at the defined IP address
* add typing hints to make it easier for 3rd party developers to use the library
* remove unused devicetype enum to support python3.3
* add python 3.3 to travis and tox, install typing module in setup.py
* Discover refactoring, enhancements to the cli tool
* Discover tries to detect the type of the device from sysinfo response
* Discover.discover() returns an IP address keyed dictionary,
values are initialized instances of the automatically detected device type.
* When no IP is given, autodetect all supported devices and print out their states
* When only IP but no type is given, autodetect type and make a call based on that information.
* One can define --bulb or --plug to skip the detection.
* renamed pyHS100.py -> smartdevice.py
* SmartPlugException -> SmartDeviceException in comments
* fix mic_type check
* make time() return None on failure as we don't know which devices support getting the time and it's used in the cli tool
* hw_info: check if key exists before accessing it, add mic_mac and mic_type
* Check for mic_mac on mac, based on work by kdschloesser on issue #59
* make hound happy, __init__ on SmartDevice cannot error out so removing 'raises' documentation
