Fix and improve UI of scroll bar menu (bug#27047)
In addition, since the Emacs manual writes "scroll bar", "tool bar" and "menu bar", use this convention in the Show/Hide menues and tooltips as well. * lisp/menu-bar.el (menu-bar-showhide-scroll-bar-menu): Make pressing a radio button in the menu actually show that it was pressed. Replace the two radio buttons to turn the horizontal scroll bar on and off with a single check-box toggle and add a separator between this and the vertical scroll bar radio buttons. Use conventional spelling. (menu-bar-horizontal-scroll-bar) (menu-bar-no-horizontal-scroll-bar): Remove, since now unused. (menu-bar-showhide-tool-bar-menu, menu-bar-showhide-menu) (menu-bar-mode): Use conventional spelling.
