Sonoff Touch EU double JUNG frame

This is my first approach on creating a basic frame, fitting a JUNG design combined with a Sonoff touch EU version.

Be careful to configure your printer for best dimensional accuracy, since the inner socket frame is exactly 1mm larger than the actual socket. So if you're off by 0.5mm, you might have problems sliding the socket in.

If you flashed the T1 with Tasmota and expirience the very bright blue LED behind the wifi symbol:
* open Tasmota config page
* enter SaveData 1
* LedState 0
* SaveData 0

I've added a new "thing" with printable components [here](https://www.thingiverse.com/thing:3410597).


CHANGELOG:

* 2019-02-01: Small fix for inner socket frame sizing
* 2019-01-31: Strengthened the walls of the socket frame
* 2019-01-30: Minor fixes, added inner frame to sonoff frame, cleaned up design
