update for usermessages

wled.h:
- Don't use Serial directly -S2 as S2 serial driver is buggy.
- added USER_FLUSH macro
wled.cpp
- replace fluh with FLUSH
- print ArduionoOTA info (if enabled)
wled_server.cpp:
- added userlog info after file upload.
pinn_manager:
- don't show "(default)" is the PIN is actually assigned to HW drivers
- bugfix for getPinOwner()
