i want to use system fonts, how to do that ?

[Nourepide]

Now available in dea35a2.

Changes in config:

Removed fonts_folder_path array. Added fonts object with the following properties:

• folder_path is now string.
• system_fonts boolean. false by default.
• user_fonts boolean. false by default. Doesn't affect on Windows.

Thank you for your suggestions!
