1. Fixed crash on OSX after change of the settings layout (PreferencesDialog should be destroyed before call of recreate_GUI)
2. Fixed dialog message during GUI recreation
3. In PreferencesDialog changed radio buttons view (under OSX they were bold)
4. slDlg mode - fixed switching between main frame and settings dialog (dialog->SetFocus() doesn't work under OSX, so we just hide it and show again)
