Add the lodelsites directory to the autotools chain. Note : for the moment it's a dirty POC, we have to do it in a cleaner way...

Theorically all of those imports were tested by unit testing, but we've got no inssurance about that.
And even if unit tests had check for syntax errors, all pieces of code were not tested. We cannot
be sure that an import was missed or forgotten...

Test passes
