Feature/update md b
This PR adds:
- the last MdB given in Pau
- the org file for the Medit MdB
Adding org files in the content
directory breaks the home page (the org file is interpreted and new items are appended). To bypass this, a new static
directory and subtree has been added to host org files.
It fixes some broken links toward old MdB (links have been checked from the most recent MdB to the MdB on openscad, issues have been created for the links of this period that I have not been able to fix ).
