- Fix global variable 'quests' (quests/init.lua) - Fix minetest.register_on_dignode's function to handle the rare case where 'digger' == nil (mff/mff_quests/init.lua) - Made the only available quests (yet) more explicit (mff/mff_quests/init.lua)
- Updated fonts and sign_lib - Did some remove_whitespaces
