Engines like Pexels provide images that one would more likely expect in a
category named ``stock_images``.
By classifying engines like Pexels more precisely, we enable a more specific
handling of them, which also helps to avoid mixing them with the more general
image search on the internet. [1]
We leave these engines *enabled* by default, take them out of ``images`` and
move them into the specialization ``stock_images``.
This makes it possible, on the one hand, for the admin to configure a tab in the
UI, and on the other hand, the user can always select the group directly using
the search syntax ``!stock_images ...``.
What we need to keep in mind:
1. Technically speaking, there are no subcategories in the strict
sense. Organizationally, the *subcategories* are derived from the
`categories_as_tabs`.
2. From an admin’s perspective, `categories_as_tabs` is the tool for
structuring their content.
3. In the context of “enabled/disabled by default”: We should avoid having
the admin have to activate many individual engines when they want to
structure their content (UI tabs).
So if we leave an engine enabled by default and **move** it from `images` to a
new category, the admin only needs to add the new category to
`categories_as_tabs` to restructure their content. If the new category is also
part of the translations (see `searx/searxng.msg` in this PR), this UI structure
would also be available internationally.

- Modify engines to create/fetch an URL for the thumbnails
- Modify themes to show thumbnails instead of full images.
In Courgette, the result is not very beautiful. Should we change it ?
Lots of Flake8 corrections
Maybe we should change the rule to allow lines of 120 chars. It seems more usable.
Big twitter correction : now it outputs the words in right order...
Allow to search for images on 500px. It doesn't use the official API, but the page result. Less stable, but less API key to possess...
Two engines were necessary for Searchcode because there are to search mode : search for documentation or search for code example. Both use open APIs.
