widgets: add progress-bar widget implementation

[Memoraike]

Adds a new widget type CScale. With this widget and functionality in #653 it is now possible to implement such things:

Details

• config: introduce special category and config values for scale
• renderer: integrate scale widget into widget creation
• scale: implement CScale class with drawing and timer functionality

I think 'progress-bar"/CProgressBar would be a better name.

Is the duration purely handled by the animation speed? How do you sync the song's progress with the progress of the shape widget?

I think 'progress-bar"/CProgressBar would be a better name.

Is the duration purely handled by the animation speed? How do you sync the song's progress with the progress of the shape widget?

I was inspired by eww, but I agree that CProgressBar current implementation describes it better.
