FPP Rediscover and KeepOpen (plus a few more FPPConnect enhancements)

[cybercop23]

Few more FPPConnect changes:

• Some suggestions around FPP Connect #5039 Keep window open to upload to multiple playlists
• Rediscover button if you forgot to turn on controllers
• Additional sort on Upload column, not saved, but will be based on previously sorted order (for PatD)
• Right click Upload Outputs on controller for faster/easier uploads when you screw things up
• New/never seen controllers will not be checked for Upload or have Media checked - let the user decide
• Made Hostname case insensitive for those with less OCD that mix their ctrl names (Pat D and Ron A)
• Use UUID as the key for saved settings to reduce the false lookup when DHCP ctrls change IP - if no uuid, falls back to IP
• Reporpose BatchRenderSelect to be more generic and added logic to save and select failed sequences
• Added extra logging for FPPConnect sequence uploading to each instance - include bytes sent
