Phenix update: simple fix

There is a simpler fix to the phenix update issue mentioned earlier today: in $XIA2_ROOT/Applications/xia2.py change


sys.path.append(os.environ['XIA2_ROOT'])

to

sys.path.insert(0, os.environ['XIA2_ROOT'])

close to the top of the file. This will override the discovery process for where dxtbx can be found. This is included in the 0.3.6.0 update also.
