nwgbar: Better Shorcuts

[Figuera]

The current way of setting shortcuts in nwgbar is somewhat limited. You can only use the Alt key as the modifier and the other key has to be present in the name.

Can't we just add another option to the JSON file in other to more freely define shortcuts, how about:

[
  {
    "name": "Lock screen",
    "exec": "swaylock -f -c 000000",
    "icon": "system-lock-screen",
    "cmd": "Mod1+l"
  },
  {
    "name": "Logout",
    "exec": "swaymsg exit",
    "icon": "system-log-out",
    "cmd": "Mod1+l"
  },
  {
    "name": "Reboot",
    "exec": "systemctl reboot",
    "icon": "system-reboot",
    "cmd": "Mod1+r"
  },
  {
    "name": "Shutdown",
    "exec": "systemctl -i poweroff",
    "icon": "system-shutdown",
    "cmd": "Mod1+s"
  }
]

Maybe enabling multiple modifiers is more work than it is worth since using another option instead of the "_" will solve must of my issues.

I'm not sure it can be done using standard Gtk methods. I'll check what can be done after #195
