Subject: [PATCH] chat: peer-switch strip, back button moved to flyout header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Switching conversations used to require bouncing back to the list view
and picking from there. Now the thread view has a horizontal peer
strip at the top: one click hops to another conversation, active tab
is highlighted and auto-scrolls into view, unread peers show a dot.
Scrollbar is hidden — vertical wheel delta is redirected to horizontal
scroll so the user can slide the strip with the mouse wheel when it
overflows.

In-thread header is gone; the back button moved next to "chat" in the
flyout header and only shows while a thread is open. Peer name stays
visible via the active tab.

Bumps to 1.9.3.
