Auto reconnect controllers

[Yamakaky]

Use case : I use a joycon as a desktop remote. You can turn it off with the sync button, but when you reconnect it you have to scan for controllers in jsm.

I'll have to look into whether this'll affect smoothness of everything else. Maybe it'll only scan when no controllers are connected. But yeah, I'll look into it.

For my use case, scanning like every second when last controller disconnects is enough. As a more robust solution, maybe scan when a Bluetooth controller connects?

Alternatively, only reconnect known controllers with same bindings, and use the cli command to add new ones?

Next update will have a tray icon with a context menu entry to reconnect. Should be more user friendly than typing the command.

It's better, but it doesn't really address my use case.

We haven't implemented a solution to this yet, but it seems like a useful one to have for the next update.
