fix running files from file browser's context menu * main-window.cc(run_file_in_terminal): new slot for run_file_signal (run_file_callback): callback for running files after checking the path * main-window.h: new functions run_file_in_terminal und run_file_callback) * files-dock-widget.cc(constructor): connect signal to slot for running files (contextmenu_run): emit run_file_signal with QFileInfo as parameter * files-dock-widget.h: run_file_signal has QFileInfo as parameter * file-editor-tab.cc: removed function run_file_callback (run_file): get file info of current file and emit run_file_signal (file_in_path): moved to octave_qt_link allowiung access from other widgets, updated calls to this functions * file-editor-tab.h: new run_file_signal with QFileInfo, removed functions run_file_callback and file_in_path * file-editor.cc(add_file_editor_tab): connect signal to slot for running files * octave-qt-link.cc/h(file_in_path): moved from file-editor-tab and made static
