Publish a cleaner version on Pypi

[delhomer]

For now on Pypi, there are two publication problems:

• markdown is wrongly rendered;
• images are not depicted.

(See https://pypi.org/project/deeposlandia/0.6.1/)

Solution for first problem

An argument is missing in setup() function : https://packaging.python.org/specifications/core-metadata/#description-content-type. One has to add long_description_content_type="text/markdown".

Solution for second problem

There seems that Pypi does not support relative paths; hence one should specify the image absolute paths in the README file.

For similar issue on other projects:

• https://github.com/senaite/senaite.sync/issues/61
• https://github.com/dhimmel/obonet/issues/12
• https://github.com/pypa/warehouse/issues/5246

The problem is also discussed there: https://stackoverflow.com/questions/41983209/how-do-i-add-images-to-a-pypi-readme-that-works-on-github.

As a remark there are some cons with managing the image rendering problem with absolute paths towards master branch. See https://github.com/GillesPy2/GillesPy2/issues/213 for more details on this point.
