* Add support for MagicHome RGBWW LED strip

This adds support for MagicHome 5 channel LED strip. It is using ESP8285 board, labelled as ESP-M4, has 5 powerful MOSFETs (M3006D, up to 80A! continuous/160A peak) at 12-24V. They are driven by smaller transistors. Red LED is connected to 3.3V power supply, and can't be controller. Green LED is connected to GPIO. Pin mappings:
BTN IO0
R Q8 Q2 IO14
G Q6 Q3 IO12
B Q9 Q4 IO13
WW Q10 Q5 IO15
CW Q7 Q1 IO5
GREEN_LED IO2
Looks like the same board is used in another product which has support for RF remote, but mine doesn't, so I don't include RF config, if yours has it should be a simple copy/paste job to add it.

* Add config for push button

* Fix copy/paste mistake

* Turn on/off LEDs using the push button

Added initial support for Oukitel Smart Switch. This is a 2 outlet plug
that has the same pinout as the YiDian XS-SSA05.

* Added the configuration for the second generation OBI devices.

* Added link to the OBI Wifi Schuko Plug V2 as well as included the device in the readme.

* Restored the default configuration accidentially changed by a previous commit.

* Renamed the OBI-V2 device to EUROMATE_WIFI_STECKER_SCHUKO_V2 as suggested by mcspr.

* Fixed spelling of comment to the proper wording Schuko.

Do not change the default env
