Where possible remove limitations

So, have been using Aimless for a little while now, which does not need recompiling for lots of batches. Using this with Reindex replaced with Pointless means you can now process data sets with many many images. By way of a test case: 70 180 degree sweeps @ 1 degree / frame from a small molecule crystal processed fine. This is most likely to be useful with Pilatus data. Would suggest -3da (and a local install of recent Pointless / Aimless versions) to do this kind of thing. Will be released shortly unless you want to get it from svn.
