Subject: [PATCH] packages/fff: Add package fff-web-mqtt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With this package the mqtt settings can be configured over the webui.

Each user can use its own mqtt broker or a broker from another user.
This means that the user has a free choice of where to send or get data.
