The old searx theme was a copy of the flask theme.  In the meantime this theme
is available from the python module pallets-sphinx-themes.

This patch makes pallets-sphinx-themes as a (dev) requirement and drops most of
the old and obsolete searx theme settings/files.

- add build & dist folder to .gitignore
- justify indentation of build messages (makefile.python)

[mod] tidy oscar HTML output

RFC: Makefile based boilerplate for python projects

[fix] Update xpaths for new Google results page

Adding a CR in  some files and in others not,  is  a good starting point for a
DOS+Unix mess we all have already seen in many projects.

Patch fixes all files matching (even those comming from grunt's build)::

   find ./searx -exec file {} \; | grep CR

BTW: Same with mixing TAB and SPACE indent styles in one and the same file.  So
if sources are tuched here in this patch, its also fixed.

[fix] mojeek engine

Fix python 3.8 compatibility 

The .dir-locals.el set the project's python enviroment for the emacs tasks like
flycheck or jedi.  The py-environment has to be next to <repo>/.dir-locals.el::

    ./local/py3

To setup such an environment build target 'pyenv' or 'pyenvinstall'::

  $ make pyenvinstall

TL;DR

Alternatively create the virtualenv, source it and install jedi + epc
(required by `emacs-jedi <https://tkf.github.io/emacs-jedi>`_)::

    $ virtualenv --python=python3  "--no-site-packages" ./local/py3
    ...
    $ source ./local/py3/bin/activate
    (py3)$ # now install into the activated 'py3' environment ..
    (py3)$ pip install jedi epc
    ...
