[doc] rearranges Settings & Engines docs for better readability We have built up detailed documentation of the *settings* and the *engines* over the past few years. However, this documentation was still spread over various chapters and was difficult to navigate in its entirety. This patch rearranges the Settings & Engines documentation for better readability. To review new ordered docs:: make docs.clean docs.live Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

Definitions`_. The linked API documentation can sometimes be helpful during
reverse engineering. However, we cannot use it in the freely accessible WEB
services; not all parameters can be applied and some engines are more *special*
than other (e.g. :ref:`google news engine`).
