disable some global shortcuts when editor gets focus to prevent conflicts * file-editor-tab.cc (constructor): connect signal from the qscintilla edit area about focus with the related new slot; (edit_area_has_focus): new slot for the focus signal from qscintilla edit area emitting a signal for enabling/disabling the common edit shortcuts * file-editor-tab.h: new slot edit_area_has_focus, new signal set_global_edit_shortcuts_signal * file-editor.cc (add_file_editor_tab ): connect new tab signal set_global_edit_shortcuts_signal with the related slot in main_window; (copyClipboard, pasteClipboard, selectAll): removed these functions because the related actions are triggered editor shortcuts * file-editor.h: remove copyClipboard, pasteClipboard, selectAll * octave-qscintilla.cc (focusInEvent, focusOutEvent): handlers emitting the signal about the focus state of the edit area * octave-qscintilla.h: new focus signal qsci_has_focus_signal, focus event handlers * main-window.cc (set_global_edit_shortcuts): new slot dis-/enabling the common edit shortcuts depending on focus of edit area * main-window.h: new slot set_global_edit_shortcuts
