Automate Launch at Login

[matiaz]

It would be good to automate the process of adding the app to the "Launch at Login".

I'm thinking on adding an option in the preferences popup and let the user clic on it to add it to "Launch at Login". Maybe adding a check to enable or disable that feature.

In this menu:

@matiaz I was thinking about this feature as well and after an investigation, I found that there isn't any nice way of doing that.
Apple has some classes, which can access the login items, read and modify them, but those APIs are deprecated since macOS 10.11, for example, this is the login item object class - https://developer.apple.com/documentation/coreservices/klssharedfilelistsessionloginitems

Because these classes are deprecated, I'm hoping that they will provide something for us, which can be used now, but I haven't seen any updates or new APIs for that.

And because these APIs are already deprecated a long time ago, I don't want to put them in the codebase.
