This commit hard-coded the Ubuntu font for the UI: 11a3b51

While this might look more integrated for Ubuntu Unity users, everywhere else (GNOME, KDE, MATE with other setting or another distro, ...) it doesn't. Having sans-serif as an alias which I can change to a font I want is better IMHO.

The best solution probably is to use the same font that menus are using, e. g. the system GUI/Gtk/system font. Is there a way to access this, maybe similar to -apple-system or BlinkMacSystemFont?
