fix saving modified files when closing editor tabs or octave
* file-editor-tab.cc (closeEvent) also ignore evnet when file has
to be saved, it is directly removed after saving now; in case closing is
accepted, emit the related signal to the editor;
(check_modified_file): call check_file_modified with false as new boolean
parameter indicating that file should not be closed afterwards
(check_file_modified): new boolean parameter for removing the file after
checking for modification and possibly saving; use exec for the dialog
for directly getting the result without extra finish signal/slot; if
desired, call save_file from here;
(handle_file_modified_answer): removed obsolete slot for dialog result
(do_save_file): emit signal that tab could be closed now
* file-editor-tab.h: new signal tab_ready_to_close, removed slo
handle_file_modified_answer, slot check_file_modified with new
boolean parameter
* file-editor.cc (check_closing): if closing is not canceled connect
tab signals on being ready to close instead of directly closing all tabs
and store the number of tabs that have to be closed;
(handle_tab_ready_to_close): slot for tab ready to close signal, decreasing
number of tabs to be closed until it reaches zero and then close all tabs
and the editor itself;
(closeEvent): ignore event even when all tabs should be closed because
editor will close itself after all tabs are closed
* file-editor.h: new slot handle_tab_ready_to_close, new class variable
m_number_of_tabs for the number of tabs, for which the editor has to
wait for closing
