Issue: Assign Categories to Multiple Wiki Articles

Moving to the Beta 1 milestone in the interest of keeping inline moderation simple for now and releasing Alpha 1 ASAP.

Originally requested for 3.0.0 RC 1.

Implemented in the next release, 4.0.4. This can now be accomplished by using the "Add Listing" option in the category view. Previously this allowed you to add one page at a time, but now it will accept multiple selections and add them all. In theory, this new functionality should also transfer to books, allowing you to add multiple pages as chapters in bulk.

It should be noted that the reverse was added in 4.0.15: Remove multiple pages from a category simultaneously using inline moderation from the category's page-list.

In 4.1.x, the inverse of the 4.0.15 function will be possible: Remove multiple categories from a page simultaneously via inline moderation (from the page's category list). Before 4.1.x, this could only be done via the Edit tab.

Another variation that was completed for 4.1.x is the inverse of the OP's request: Add multiple categories to a page simultaneously from the page's category list (tab called Categories That List This Page) without going to the Edit tab.

P.S. These three variants were additionally added for the other types which support one-to-many relationships: Feeds and Translations.
