From 494bd674a98bc9f2889acad0fda3ff4c77c641b5 Mon Sep 17 00:00:00 2001
From: Tobias Wölfel <tobias.woelfel@mailbox.org>
Date: Fri, 24 Jul 2020 10:36:19 +0200
Subject: Add flag based search options

Provide search and filter with the option to specify more flag based
conditions.
Use '-x <flag>' to search for messages with a flag (seen, answered,
flagged) and '-X <flag>' to search for messages without a flag.
