* 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
