Add clock interval configuration

[gizabit]

Allows configuring the clock update interval for people who can't live without seconds. 🙂

This also requires the following changes in the dotfiles repo.

1. add interval to the clock config in .config/waybar/modules.json

  "clock": {
    "format": "{:%a %Y-%Om-%Od  %H:%M:%S}",
    "on-click": "ags -t calendar",
    "interval": 60,
    "tooltip": false
  },

2. create the settings file .config/ml4w/settings/waybar_clock_interval.sh

60

Let me know if you're interested in this change and would like me to create a pull request in the dotfiles repo as well.

@gizabit Sounds interesting and easy to implement. I will add this feature for the Dotfiles 2.9.7
