Part of #1736: the toolbar without group labels, and the All Tools drawer's groups, flyout menu and Show section

- Preferences › User Interface › Show Tool Group Labels is off as it
  ships: the toolbar sets its groups apart with a faint dash, as the
  Basic and Advanced toolbars of the public toolbar reference do (the
  categories there are the Getting Started toolbar's). It no longer cuts
  "Navigate" to "Navi...". The labels are a preference away.
- The All Tools drawer lists the tools one per row (icon, full name,
  shortcut on the right), each flyout group framed together under the
  heading most of its tools have (the Pencil's group, led by the Shaper,
  under Draw). Tools already in the toolbar stay dimmed; dragging and
  picking are as before.
- Its ☰ menu has Reset and the Basic and Advanced toolbars, the drawer's
  flyout menu of the reference.
- Its Show section shows or hides the controls under the toolbar's tools
  (Fill and Stroke, Coloring, Draw Mode, Screen Mode), as the reference
  describes; `toolbar.show {control?, on?}`, saved with the preferences
  (`ui.toolbar_show`, all on for older ones). Edit Toolbar's ••• stays.
- New strings in every catalog.

 The Contextual Task Bar: its handle (the grip at its left end) drags it anywhere on the canvas, which always holds
 it whole, also when the window shrinks. Unpinned, the bar keeps that offset as it follows the selection, until
