Webapp v12.0.0

This release introduces Notebooks, a new Markdown-powered channel type with folder organization, bulk import for existing files, and clear-web publishing, while renaming the old "Notebook" type to "Bulletins" ahead of eventual deprecation. You can also now reorder pinned items on the Home screen, and fixes address premature bot thinking indicators, stale invite selections when creating a second group, persistent join errors, and non-functional group template cycling.

• Adds a new channel type, Notebooks. Notebooks are powered by pure Markdown, are organized by a folder hierarchy, and are legible to Tlonbot. We are still working on adding comments, image uploads, read-only permissions, and mention support to reach feature parity with previously-named "Notebook" channels.
• Renames said previously-named "Notebook" channel type to "Bulletins," which we will eventually deprecate.
• Adds support for bulk-importing existing folders of and individual Markdown files into a Notebook channel.
• Adds clear-web publishing for Notebook entries.
• Adds the ability to reorder pinned messages / DMs on the Home screen.
• Improves channel message pinning by deleting the pinned message from both the message log and the channel's pinned posts.
• Fixes an issue where Tlonbots would indicate they are thinking, then drop the indicator before the task was complete.
• Fixes an issue where attaching a link to a message with circular redirects could crash the ship.
• Fixes an issue where inviting people while creating a group, then creating a second group would show the selection from the first group.
• Fixes an issue where failing to join a group via the "Join a group with code (reference)" would persist the error even after entering a valid group.
• Fixes an issue where cycling through group templates in the "Create a group" dialog did nothing.

This release also enables Markdown Notebook channels on the native smartphone apps.

The channel type formerly known as "Notebook" (blog-like with a WYSIWYG editor) is now called "Bulletin." We will provide deprecation details for this channel type at a further date.
