Allow configuring how double click opens files

[jriegel-unitb]

When double-clicking a file it uses the system opener to open the file (xdg-open in my case). As far as I can see there's no way to change that behaviour in broot itself. For the sake of consistency there should be a way to configure what double click does or at least what the default file open behaviour is.

I tried these settings but they don't seem to change the double-click behaviour

You're right. I'll look into it.
