This patch adds a set_system_fonts() IPC API that takes the two main font queries as parameters. We'll probably expand this with additional queries when we figure out what they should be. Note that changing the system fonts on a live system mostly takes effect in newly launched programs. This is because GUI::Widget will currently cache a pointer to the Gfx::FontDatabase::default_font() when first constructed. This is something we'll have to fix somehow. Also note that the settings are not yet persisted.
