allow to cancel exiting if editor tabs are modified and exit is requested in gui * file-editor-interface.h: new function check_closing * file-editor-tab.cc (ctor): set default for app_closing to 0 (not closing); (check_file_modified): dialog boxes for modified editor tabs depending on app closing or not; (conditional_close): no slot, but ordinary function returning close result; * file-editor-tab.h: conditional_close is function, not a slot; _app_closing is now int for closing from gui, from octave, not closing * file-editor.cc (dtor): calling new function check_closing if there are open tabs (exit requested octave), do not save session here since the tabs might already have been closed; (check_closing): new function saving session info and closing all tabs, stop closing tabs and returning false if user cancels exiting if there is a modified tab; (request_close_file, request_close_all_files, request_close_other_files, handle_tab_close_request): use conditional_close instead of signal; (construct): do not connect old signal for closing the tabs * file-editor.h: remove signal fetab_close_request, new function check_closing * main-window.cc (confirm_exit_octave): call file_editor::check_closing before really closing the app

Summary of important user-visible changes for version 4.0:
---------------------------------------------------------

 ** For compatibility with Matlab, the "backtrace" warning option is now
    enabled by default.

 ** The preference

      do_braindead_shortcircuit_evaluation

    is now enabled by default.

 ** The preference

      allow_noninteger_range_as_index

    is now enabled by default and the warning ID

      Octave:noninteger-range-as-index

    is now set to "on" by default instead of "error" by default and "on"
    for --traditional.

 ** polyeig now returns a row vector of eigenvalues rather than a matrix
    with the eigenvalues on the diagonal.  This change was made for Matlab
    compatibility.

 ** Other new functions added in 4.0.0:

    validateattributes

 ** Deprecated functions.

    The following functions were deprecated in Octave 3.6 and have been
    removed from Octave 4.0.
                                           
      cut                polyderiv        
      cor                shell_cmd        
      corrcoef           studentize       
      __error_text__     sylvester_matrix 
      error_text         

    The following functions have been deprecated in Octave 4.0 and will
    be removed from Octave 4.4 (or whatever version is the second major
    release after 4.0):

      allow_noninteger_range_as_index
      do_braindead_shortcircuit_evaluation
      
    The internal function atan2 of the sparse matrix class has been deprecated
    in Octave 4.0 and will be removed from Octave 4.4 (or whatever version is
    the second major release after 4.0).  Use the Fatan2 function with sparse
    inputs as a replacement.
