Font settings

This section allows to configure several fonts used in Worker:
- Global font: This is basically the main font used everywhere where no other specific font is set.
- Font for action and path buttons: This font is used for the button banks and path banks in the main window.
- Font for left list view: This font is used for the left panel in the main window.
- Font for right list view: This font is used for the right panel in the main window.
- Text view font: This font is used as the main font for the actual text in the text viewer.
- Text view alternative font: This is an alternative font for the text viewer that can be dynamically selected on demand.
- State bar font: This is the font used for the top (by default) state bar. It is beneficial to use a mono-spaced font since the space reserved for file and directory counts are calculated dynamically to have enough space for both selected and total numbers without changing the text content width.
