XDS patch

Hi Folks,

As it seems that the XDS problem is becoming more of a ... problem, I have put together a file containing the changes from 0.2.7.2 to bring it up-to-date with respect to the XDS changes, but hopefully nothing else as there are a couple of developments in flight.

If you download

http://www.ccp4.ac.uk/xia/XDS-patch.tar.bz2

Then unpack it as follows:

tar xvfj XDS-patch.tar.bz2 -C $XIA2_ROOT

xia2 should be updated to work with the latest version! The next proper release will contain this, but I have a lot of other things to go in there too...
