doc: proofread of the all reST sources (no content change)

Normalize reST sources with best practice and KISS in mind.

to name a few points:

- simplify reST tables
- make use of ``literal`` markup for monospace rendering
- fix code-blocks for better rendering in HTML
- normalize section header markup
- limit all lines to a maximum of 79 characters
- add option -H to the sudo command used in code blocks
- drop useless indentation of lists
- ...

-Searx admin interface: manage your instance from your browser

+Searx admin interface

-One of the biggest advantages of searx is being extremely customizable. But at first it can be daunting to newcomers.
-A barrier of taking advantage of this feature is our ugly settings file which is sometimes hard to understand and edit.

-To make self-hosting searx more accessible a new tool is introduced, called ``searx-admin``.
-It is a web application which is capable of managing your instance and manipulating its settings via a web UI.
-It aims to replace editing of ``settings.yml`` for less experienced administrators or people
-who prefer graphical admin interfaces.

-Since ``searx-admin`` acts as a supervisor for searx, we have decided to implement it
-as a standalone tool instead of part of searx. Another reason for making it a standalone
-tool is that the codebase and dependencies of searx should not grow because of a fully optional feature,
-which does not affect existing instances.
