Merge branch 'builtin-filters': four built-in query filters

Items 93, 95 and 90. The query row starts with Unread, Inbox, Flagged and Sent,
shipped by the application rather than pinned by the user, and they compose with
the account dropdown instead of resetting it. Item 90 is absorbed: the button
that cleared the account selection is no longer a saved query at all.

Item 95 was found by hand testing this and is not caused by it: no entry in the
saved query overflow menu had ever been runnable, because Qt emits no triggered
for an action that owns a submenu.

 ### Added
 
+- **Four built-in filters on the query row: Unread, Inbox, Flagged and Sent.**
+  They are part of the application rather than saved queries you happened to
+  pin, and they **compose with the account dropdown**: select an account, hit
+  Unread, and you get that account's unread mail instead of everyone's. With
+  "All accounts" selected they span every account, as before.
+
+  Changing the account still runs nothing on its own. The dropdown chooses the
+  scope and the button is what queries, so you can pick an account and then
+  decide what to look at.
+
+  Your own saved queries are unchanged and keep the behaviour they had: one
+  that names no account still clears the selection, because a saved query says
+  exactly what it shows.
+
 - A third right-click search action, **Exclude from search**, wherever the
   other two are already offered: the message pane's header and body, a tag

+- **A saved query in the "More queries" menu could not be run.** Clicking one

 ### Upgrading
 
+**The query row now starts with four buttons the application ships**, so your
+own pinned queries sit after them. If you had saved queries named Unread,
+Inbox, Flagged or Sent, you will see two buttons with the same name: yours and
+the built-in one. Right-click yours and choose **Move to menu** to keep the row
+readable.
+
+Your **Sent** button is a special case and is moved for you. Version 0.19.0
+turned the old hardcoded Sent button into a saved query in
+`~/.config/qtmaildir/queries.json`; that entry now duplicates the built-in
+filter, so it is unpinned automatically on first launch. It keeps its name, it
+keeps working, and it is in the **More queries** menu. Nothing is deleted, and
+pinning it again restores it if you prefer it there.
+
+The difference worth knowing: the built-in filters **use** the account
+dropdown, while a saved query **sets** it. Selecting an account and clicking
+Unread shows that account's unread mail; selecting an account and clicking a
+saved query that names no account clears the selection first, as it always
+has.

 Reading a thread now means expanding it and clicking down its replies. Nothing
 in your config changes, and no habit built on the reply rows is affected, but
 the pane will show one message where it used to show a conversation.
