keep a buffer dirty flag and display infos about the current buffer in the interfaces (including the dirty flag)

 * was a bit tricky because the Scintilla SAVEPOINTS cannot be (fully) used
 * when a file is loaded or saved, a Scintilla SAVEPOINT is set
 * SAVEPOINTLEFT notifications are used to set a buffer dirty
 * SAVEPOINTREACHED notifications are useless since Scintilla does not consider the saves themselves to be undoable
 * GTK interface displays infos in window title bar
 * NCURSES interface has also been updated and cleaned up a bit. Infos are displayed in a new info line.
 * NCURSES: fixed popup display after terminal resizing
