[interim fix] static files can't be delivered by HTTP.

Since PR 932 [1][2] static files can't be delivered by HTTP server any longer.

This patch makes the hash paramter in the URL of static files:

    /static/themes/simple/css/searxng.min.css?5fde34a74bc438c7b56ec8c6501e131cc9914bd8

optional.  By default the hash parameter is disabled.

HINT:

  Instances that do not deliver static files by their HTTP server and have a
  long expire time [3] should enable this option.

----

This is only a interim solution, on the long run:

    make static.build.commit

creates files including the file name:

    css/searxng-5fde34a74bc438c7b56ec8c6501e131cc9914bd8.min.css

and a mapping.json with this content[4]
