Allow Idle Disconnect time to be set lower than 3600 seconds.

I recently discovered that the minimum time you can set for Input Idle Disconnect Time Seconds is 1 hour (3600 seconds).   This is not mentioned when you change the setting, nor does it prevent you adding lower times.  It simply ignores the time you enter and fails to disconnect an idle session.

Please fix this and allow lower times - for people that use this solely for remote support purposes, there is no need to have the default idle timeout to be 1 hour.  Realistically, there  is no need to have an arbitrary minimum time - leave it to us to decide what we want.
