Use system font for texts

long story short, many devices have different system fonts and some even have the ability to set a custom font for the whole UI.

so, instead of having to select a font for any text items which then gets forcibly applied to it, an option should be made to not set a custom font but to use the system's setup. in fact that probably should be the default in my opinion.

Changing the default would be hard but providing an option to use the system fonts should be feasible, will look into this

Using "Community Material Font" sets the widget/wall font to the system font. I have no idea how it works, but it does. I constantly change my font with Substratum, and widgets using CM Font adapt to it after a reboot.
