Discarded initFileEditor, instead put that in the constructor. Speedup for updating the symbol table by lowering complexity from n² to n. Fixed problem with hangup on quit. * FileEditor: Removed initFileEditor, put that code into the constructor. * WorkspaceModel: Simplified updating the symbol table. * OctaveLink: Add quit_allowed = true to prevent hangup on quit.
