* Support changing the bulb color for tplink smartbulbs, related to #8766
* existence of ATTR_RGB_COLOR in kwargs, not just its existence...
* return modified supported features
* rgb-hsv conversion utils from hass return bogus values (at least for this device), so doing conversions directly with colorsys
* add typing & documentation for color model conversions
* make linters happy
* cast hsv to integer before passing it to the backend library
* make sure the bulb is on before adjusting the other settings
* allow floats as inputs for conversions, return always integers
* use typing hint in the parameter list instead of at assignment
* do not assign local color state inside turn_on, but let update handle doing it
* use forward declaration for typing, fixes travis requirements build hopefully
* rename hsv and rgb
* remove type-checking check, forward declarations should work just fine without it
* disable (broken) pylint warnings, these can be removed after astroid is updated from 1.4.9 to 1.5
* Add new component for TPLink light bulbs.
* Update with result of gen_requirements_all.
* Add new component light.tplink.
* Move I/O outside of properties as per https://goo.gl/Nvioub.
