Auto Update Kando

[zunaidFarouque]

• A toggle to turn off or on the checking of available updates.
• if update is available, ask to let user
  • update Kando [^1]
  • skip this version
  • remind later (remind in 5 days?)

[^1]: if implementing it is difficult, button can say "download latest from web" to open release page of Kando to let them download by themselves.

when an update is available,

• an option can be shown in the tray menu to open the update window
• an update icon can be shown here

Thanks for the suggestion! This should definitely be added. However, I guess that whether an auto-update is possible depends on how the user installed Kando. If installed via some package manager, Kando will not have the permissions to auto-update. However, we could display a notification nonetheless.

I have not implemented something like this before (and there are currently more important things to implement) so if anybody wants to add this, just drop a note here!
