Weedo Tina2 filament runout detection

Having now a complete Marlin firmware opens a lot of new features.
Among them there is a filament runout detection section which I think is a feature every 3D printer should have.
So it's time to add one to my beloved Weedo Tina2.
One thing that was missing the Tina2 is a filament runout detection system.
So I designed one and modified my Marlin2 firmware to detect filament runout whenever the X min endstop is untriggered because the pin for this endstop is not used (I could have choose the Y max endstop pin instead which is also unused).
This feature is really a must have if you don't want to find your Tina2 printing in the air and waste time and filament on an incomplete (and therefore unusable) printed part.
My design uses one of the most common and cheap enstop you can find and works incredibly well.
Before testing it "for real", I first checked in Pronterface to make sure it triggers and will work as intended :
And here is a small video showing it in action.
