Issue 663: Stylus detector

Reported by Joerg Reisenweber, Sep 25, 2014

maybe use infrared proxi, same as for camera door
mount to bottom side of UPPER, looking thorugh two 
"windows" in lower to either stylus (no light path, aka 
"dark") or silver steel surface on backside of stylus bay 
(light path clear, "bright")
Two windows, to block bad light path reflecting from surface of 
stylus.
Might also work with one window for both RX and TX with original 
stylus which has been tested to not reflect enough light to make 
front IR proxi sensor switch to "close" state:
IroN900:/sys/bus/platform/devices/proximity# watch --interval 1 cat 
state

See attached sketch

Try to restate your system if you are still facing the issue and 
always do testing first. The https://www.australian-writings.org 
recently publish a guide about it so It might help you to fix it as 
soon as possible.
