Docs: Batch's Override Export names every output collision it numbers

The progress-doc bullet now says that folder and file names drop trailing
periods and spaces, and that Batch also numbers a name that an earlier
output, a source file in the destination folder or, for data sets, an
existing file already has.

   - Variables: when no object is bound to a variable that the data set has a value for, for example after Import Data Sets… defines new variables without binding them, choosing the data set in the Variables panel or stepping to it with the panel's arrows shows a status message, and `dataset.select`, `dataset.next` and `dataset.prev` add the message to the reply as `warning`.
   - Variables: Lock Variables (`variable.lock`, in the Variables panel's bottom bar and menu) stops variables from being defined, deleted or renamed until they are unlocked, while objects can still be bound and unbound and data sets still change and apply; the lock is saved with the document.

-  - Batch…: Override Export writes the files of an Export for Screens or Export Assets step into a folder for each source file or data set inside the destination folder, under the names the export gives them (`action.batch`). When source files have the same name without the extension, Batch adds `-2`, `-3`… to the folder or file name of each later one.

The folder and file names drop trailing periods and spaces (`a..svg` gives `a`). When two source files would get the same name that way (compared without case), or a later file's folder or file would take the name of an output an earlier file wrote, of a source file in the destination folder or, for data sets, of a file already there, Batch adds `-2`, `-3`… to the later one's name.
   - Actions panel (record/playback, persisted), generic parameter dialogs for every "…" command.
   - Actions panel: Delete Selection deletes the selected action set with its actions and keeps the other sets ([Actions panel overview](https://helpx.adobe.com/illustrator/desktop/automate-visualize-data/automate-actions/actions-panel-overview.html): "Removes the selected action, command, or action set from the panel"; `ui.actionSet.delete`). VectorCraft's own rules, which the overview does not cover: deleting a set asks first, Shift-click on a set's name selects a range of sets to delete together, the panel menu's Delete does the same, and Default Actions and the last set can be deleted. Undo does not bring a deleted set back.
   - Batch… over data sets names each file after the document and the data set (`action.batch`). It writes `/`, `\`, `:`, `<`, `>`, `"`, `|`, `?`, `*` and control characters in the data set's name as `-`, and adds `-2`, `-3`… to a name an earlier data set used.
