enable readline key bindings in terminal widget of gui (bug #36986) * TerminalView.cpp(constructor): connect signal indicating focus change to related slot of main window for setting/resetting shortcuts, (focusInEvent,focusOutEvent): emit focus change signal * TerminalView.h: new signal set_global_shortcuts_signal for focus change * QWinTerminalImpl.cpp(constructor): connect signal indicating focus change to related slot in main window, (focusInEvent,focusOutEvent): emit focus change signal * QWinTerminalImpl.h: new signal set_global_shortcuts_signal for focus change * main-window.cc(construct): connect signal emitted on terminal focus change to related slot of the editor for setting/resetting shortcuts, call new function set_global_shortcuts for initializing shortcuts (construct_file_menu): add shortcut conext for open action, class variable for exit action (construct_new_menu): add shortcut conext for new action, (construct_edit_menu): make find files action a class variable, (set_global_shortcuts): new slot for setting or resetting some shortcuts, also emits signal for child widgets * main-window.h: new slot set_global_shortcuts, new signal set_widget_shortcuts_signal, class wide variables for find files and exit action * file-editor.cc(construct): change QActions into class wide variables and add _ before variale names, do not set shortcuts, call set_shortcuts instead, (set_shortcuts): new function for setting or resetting shortcuts * file-editor.h: new function set_shortcuts, new names for QActions
