[Quick Accent] Change the font of the interface

[WangYiBen0]

Description of the new feature / enhancement

Add a selection box in the settings menu, which changes the font displaying the Quick Accent interface.

(My English is not very good, please forgive me)

Scenario when this would be used?

1. Some fonts cannot display all the characters, such as Simplified Chinese font "Microsoft Yahei".Unluckily, some operating systems cannot change the default font (for example, "中国定制版" Windows).
2. Some people have the need to change the font, in order to beautify the computer.
3. Some fonts can distinguish the similar characters. I think they are more proper.
