The rewrite addresses a problem with the tellstick hardware dropping
commands when too many simultaneous calls is being made from HA. Also fixes a bug when the dim level was changed externally.
This breaks previous configurations.
The new config for tellstick is
```yaml
tellstick:
signal_repetitions: X
```
Lights and Switches are detected automatically.
Sensors work like before because they do not share any functionality with the other devices and they also needs a complete other configuration.
The default configuration of the mFi controller generates self-signed
certificates which are valid for short periods of time, and which are
regnerated on start or as needed. This makes requests mad. Since most
people will be using the self-signed certificates anyway, add options
to let them choose non-TLS, or unverified connections if they want/need.
This bumps the mficlient requirement to 0.3.0 for proper handling of
verify=False.
The exception we were catching incorrectly referenced the client variable
in local scope instead of the module. Also, if we fail to connect we can
get a requests exception, so catch and handle that as well.
* Move S_LIGHT and V_LIGHT from light back to switch platform, to avoid
double devices showing.
* Remove MySensorsLightPlain class from light platform, since it's not
needed anymore.
* A light switch with only a switch, ie no dimmer or
RGB controls, will show as a regular switch device.
* Add mysensors binary sensor.
* Add discovery platforms to binary_sensor base component.
* Replace device_state_attributes with state_attributes in
binary_sensor base class.
* Fix docstrings.
* Add discovery of binary sensor to mysensors component.
* Add child.type as argument to mysensors device_class.
* Move binary sensor types from sensor to binary_sensor module.
* Fix binary_sensor attribute tests. Use state_attributes instead of
device_state_attributes.
* Make a flatter one level inheritance, with MySensorsLight as parent
with four children, one per light type.
* Break out helper methods. One per plain light, dimmer and RGB/RGBW
children and per update, turn_on and turn_off, nine in total. Put
these in the parent.
* Call the helper methods as needed from the child methods update,
turn_on and turn_off.
* Change name of MySensorsLightLight to MySensorsLightPlain.
* Fix module docstrings according to pep257.
* Change name of color util method from rgb_hex_to_list to
rgb_hex_to_rgb_list.
* Add unit tests for rgb_hex_to_rgb_list.
