Windows Client Updated (NOTE: that the announcement text shows both clients were updated, but upon inspection, the Mac client is still the same version)

1. Crash related to network send error avoided. A new toast shows up to restart client now shows when this occurs.
   
   
2. Fix the 'network send error alert flood' (some users get just TONS of alerts back-to-back in some error scenarios. Suppressed these alerts)
   
   
3. Popup added to invite user to share livestream URL back to JamKazam.
   
   
4. Expanded list of stun servers to add better Global support of JamKazam.
   
   
5. The session owner/creator can lock the session. When a session is locked, only the current set of users can leave & rejoin. New users are not accepted to the session. Figured this good way to keep session open until it is full. 
   
   
6. The session creator can block/eject a user from the session. The block remains in effect for all sessions the creator makes until the client is closed or the blocked user cache is cleared
   
   
7. The blocked user cache can be cleared, allowing previously blocked users to join session.
