-----------
bugfix [#19392] Typing help() in the console window freezes Blender

for now set the sys.stdin to None, this gives an error on input() or help() but better then locking up blender.
Would be nice to support for the blender console to be used as a stdin but this isnt so simple.

also quiet some warnings.
