Merge branch Mario/local_idlekick_fix (XXS merge request)

In my experience dealing with the idle-to-spectator feature, I uncovered that the idle kicking feature is functional in local matches where it may kick the host of the listen server. My request here is to disable both the idle kicking and idle spectator features while in a listen server (AKA a local match), as I believe the latter is detrimental to the gameplay and development experience.
