In the UI, enabling the "Filament Sensor" option does nothing to actually detecting and using the filament sensor attached.

Description

Title says it all. My filament sensor turns the indicator light on and off accordingly, but the firmware does not seem to really care.

Steps to Reproduce

1. Turn on Filament Sensor option
2. Install Filament Sensor
3. Be amazed at how nothing happens

Expected behavior: The Filament sensor should work

Actual behavior: It doesn't

Additional Information

This was using the official release bin file you put out. I tried creating my own to solve the problem but ran into an even bigger problem. Something along the lines of the build environment being incorrect, but if I change it to mega2560 like it asks it tells me that my "'ENCODER_PHASE_0' was not declared in this scope". Weird. This is of course using the unmodified base file.

i have a similar issue with the sensor in that it initially works but every time i try to print, it says "filament runout" then purges filament, then gets stuck on "filament runout" again and i have to reboot to clear it.
