- remove '\n' to prevent bad output (some buildin echo functions don't handle it correctly)
- tells if package config for gtk+-2.0, x11, libnotify and freetype2 are availables
- export logging functions into 'function_library' and source it from domake and doinstall
- cosmetic on logging messages to follow GNU standards (do not use dot at the end of messages)
