workaround for [#21486] Python debuger pdb don't work

setting sys.stdin to None is done so python wont lock blender when it tries to read from the input. - help() from the console does this.
Running blender with -d keeps the stdin so python debugging can work. add info in the help message about this.

eventually it might be best to replace sys.stdin with our own object which interacts with the console but this is not trivial.
