Tabs: Ctrl-dragging a tab stop moves all the stops together

In the Tabs panel, a stop dragged on the ruler with Ctrl held (Command on
macOS) moves every stop by the same distance, set in one text.tabs.set and
one undo step. The stops keep their order, alignment, leaders and Align On,
and the ruler draws them at their new positions during the drag.

Ctrl is read when the drag starts, as the Left Indent marker reads it. A drag
that would take the leftmost stop below 0 leaves it at 0, and one that would
take the rightmost past 100,000 pt leaves it at 100,000 pt, keeping the
spacing of the others. A Ctrl-drag released off the ruler deletes only the
dragged stop, as a plain drag does. A plain drag still moves one stop.

 - **The text style panel menus' Duplicate and Delete:** in the Character Styles and Paragraph Styles panel menus, Duplicate highlights the copy, as Create New Style highlights the new style, and Delete leaves no style highlighted, as the Delete button does, so Duplicate, Clear Overrides, Redefine and Style Options are disabled until another style is clicked. A highlighted style that is renamed in Style Options or deleted by a command is no longer highlighted either. The tests `panels::text_styles::tests::panel_menu_duplicate_and_delete_update_the_highlighted_style` and `a_highlighted_style_that_is_no_longer_listed_is_not_highlighted` cover this.

 - **Names of new styles and symbols:** `charStyle.new` and `paraStyle.new` trim the white space around the name they are given, as `charStyle.rename` and `paraStyle.rename` do, and refuse a name that is then empty; Duplicate names its copy from the trimmed name. `symbol.new` and `symbol.duplicate` trim the name as Symbol Options does, and `library.use` adds a library's text style under its trimmed name.

 - **Naming a new text style first:** Alt-click on New in the Character Styles or Paragraph Styles panel opens New Character Style or New Paragraph Style (`ui.newCharStyle`, `ui.newParaStyle`) with the name a plain click's style gets; OK makes the style from the text selected when the dialog opened, and Cancel adds none.

+- **Moving all tab stops:** in the Tabs panel, a stop dragged on the ruler with Ctrl held (Command on macOS) moves every stop by the same distance, in one `text.tabs.set` and one undo step; the stops keep their order, alignment and leaders, the ruler shows them moving during the drag, and a drag that would take the leftmost stop below 0 leaves it at 0, or the rightmost past 100,000 pt leaves it at 100,000 pt, with the other stops at their spacing from it. Ctrl must be held when the drag starts. Tests `panels::tabs::tests::command_drag_moves_all_the_stops_together`, `command_drag_stops_at_zero_and_keeps_the_spacing` and `command_drag_stops_at_the_largest_position_and_keeps_the_spacing`. Public reference: [Manage tab stops](https://helpx.adobe.com/illustrator/desktop/measure-and-align/grids-and-guides/manage-tab-stops.html), which says that a Ctrl-drag (Windows) or Command-drag (macOS) of a tab moves all the tab stops at the same time.
 - **Width Point Edit:** Shift-double-click enables Adjust Adjoining Width Points; plain double-click and direct opening retain the default. Tool dispatch and headless dialog tests cover neighboring widths, Undo/Redo and Cancel. Public reference: [Variable-width strokes](https://helpx.adobe.com/illustrator/using/stroke-object.html).
