Removed unused classes and added octave loop hook. * OctaveGUI.cpp: Removed header for command line parsing and command line parser. * WorkspaceModel: Optimized updated the model from the symbol table by passing pointers instead of copying. * OctaveLink: Removed polling thread. * src.pro: Removed deleted files. * OctaveCallbackThread: Not used anymore, hence removed. * CommandLineParser: Not used anymore, hence removed. * ReadlineAdapter: Not used anymore, hence removed.
