Another major overhaul.
Not much in looks, but I felt inspired to finally overhaul the configuration file functionality and a few other things while I was at it.
(even shellchecked it)
I believe the configuration options are clearer and simpler now.
I'm especially proud of the toggle/reload functionality, bound to a hotkey I can invoke the weather forecast and update or kill it. Eyecandy:
the window icon is updated to the current weather icon!
