1) seperate UI font for the remote and main displays 2) allow individual skins to load additional fonts for use in the skin (Uo to 7 extra in this first version) see CustomWPS for info on how to load a font in the skins. Code should always use FONT_UI+screen_number to get the correct user font git-svn-id: svn://svn.rockbox.org/rockbox/trunk@24644 a1c6a512-1295-4272-9138-f99709370657
