Makefile does not correctly update all po files
Since po files are updated through the DamnedLies website, they usually do not get updated when the source documents in /src get changed. This was, I assume, how the original workflow went.
For languages without a lot of contributors it can take years before they get updated. In the meantime, the po files in our repository get further out of sync with the /src xml documentation.
Even when we do a make po, a lot of po files do not get updated, unless we first touch all files in /src. We need to figure out the best way to make sure that all po files that need updating, do get updated when making the po target.
