Checking up on XDS

So the number of new-year-new-xds-why-doesn't-it-work complaints this year exceeded the energy threshold to remove the XDS version check (that, and the fact that the program has not changed how it behaves for a while now)

So, I have removed the check. I will however post when I think a new XDS build should work, and keep the checked versions up-to-date. If you like to have xia2 check for you, -check_xds_version is there for you.

However, most people don't want this it seems :o)
