Much belated xia2 0.3.3.0 release

In the usual place, changes since 0.3.2.0

• Support for new XDS build.
• Small bug fix / improvement in XDS indexer implementation.
• Capability to ptovide refined experimental geometry via XDS GXPARM.XDS - useful for polycrystal data reduction.
• Now check what you tell the program, viz:

  gw56@ws050 nonsense]$ xia2 -3d -nonsense /data/gw56/dl/Cowan/Insulin/insulin/
  Traceback (most recent call last):
    File "/home/gw56/svn/xia2/Applications/xia2.py", line 45, in

  and complain if you type in something xia2 does not understand.
• Removed a lot of cruft from the xia2 code base in preparation for some more substantial refactoring.
• Found bug which meant that the labelit beam centre computed in the setup phase was not used - mostly this is not important, unless you are using -3dii.
• Added -ice command-line argument, which will exclude measurements from regions which are typically where ice rings land. Will need to add more subtle mechanism which will allow specific regions to be excluded.
• Specifying resolution with 3d(r) pipeline now works correctly.
• Removed XDS version check by default, which was annoying every new year. If you would like to check that the XDS version is explicitly supported, add -check_xds_version to the command-line.
• Added table of scala runs to sweep name in the debug output, helpful for reviewing in polycrystal data reduction cases.
• Mosaic spread used from Mosflm is now average of all images, not the first or last image.
• Fixed header reading for new Pilatus instruments at DLS and elsewhere.
• Added capacity to pass in known globally postrefined experimental setup via -xparm GXPARM.XDS, only useful with XDS processing pipelines.
• Removed use of ccp4 printpeaks tool, which crashes on new pilatus images, replace with Mosflm for the moment. Move to replacement with labelit code at later stage planned.
