use xdg-open for default browser and file explorer in config.ron

I guess we need another method for the default terminal. Maybe something like i3-reasonable-terminal or x-terminal-emulator.

On debian, at least, x-terminal-emulator is supposed to mark the system's preferred terminal. www-browser is the same for the web browser.

Weirdly, I had to manually add firefox as an alternative using update-alternatives for x-www-browser to open it, while chrome and firefox-trunk were already added by default (chrome with the highest priority). But ya, I was avoiding adding x-terminal-emulator or x-www-browser because they may not work on non-debian distributions.

Just noticed that pressing Super+f (or running xdg-open ~) opens RawTherapee instead of Nautilus on my system. The Default Applications in Gnome Control Center doesn't have an option to change the default file browser, we should make sure that cosmic-settings has that option.

The fix was easy though.

$ xdg-mime query default inode/directory
com.rawtherapee.RawTherapee.desktop
$ xdg-mime default org.gnome.Nautilus.desktop inode/directory
