[9.0][website_blog_excerpt_img] Migrate, LGPL. (OCA#298)

* [8.0][website_blog_excerpt_img] New layout for blog.

Add an excerpt and an image taken from the post to the blog summary page.

To make this work, these open PR need to be merged:

- OCA/server-tools#354
- OCA/server-tools#355

* Default value for `background_image` is usually something like `http://localhost/blog/our-news-1/post/blog-post-title-3?enable_editor=1`, not empty, so fixing here to avoid failure loading empty covers.

* Simpler logic and better layout in phones.

Fix bug in generated images, add convenient classes.

The output of some images was a generator instead of an URL.

I add excerpt-txt and excerpt-img classes for make life easier for
themes.

Add basic styling.

All images now have the same height, and excerpts are 80 words long,
which mostly matches the image height.

Update for upstream module rename.

* OCA Transbot updated translations from Transifex

* [9.0][website_blog_excerpt_img] Migrate, LGPL.

Relicensed, migrated, new tests.

+
+Known issues / Roadmap
+======================
+
+* Right now, it will display the cover image if available, and an image
