Cleaned up code. * .hgsub: Removed IRC Widget. * gui.pro: Removed dependency on IRC Widget and removed files. * class FileEditorMdiSubWindow: Renamed to FileEditor. File editor windows are now independent windows, thus removed the extra close button. * MainWindow: Removed MDI Area and replaced it with the terminal instead. * BrowserWidget: Removed browser widget. * SettingsDialog: Rearranged settings for the editor, removed tab for shortcuts. * OctaveCallbackThread: Raised update intervals from 0,5s to 1s. * OctaveLink: Replaced signals names for triggering updates on the symbol table. * WorkspaceView: Adjusted connect statements to fit the new signal names.
