Add slice number to job name

When submitting several jobs with different slices otherwise the SGE queue
was quite confused...
sls/work version of stacked scan
added optionparser to stacked scan and the ability to adjust the correction factor, removed all of the old command line garbage
adding the option to put in the number of blocks or scans to make
updating grecoman (it did not even start before) and adding the rsync command from the wiki
updated multiscanViewer to work with scans in different directories using the -s argument, added a new script to process the command_list.txt to fix arguments (could be useful for resubmitting all reconstructions with same min and max values etc)
Merge branch 'master' of https://bitbucket.org/psitomcat/beamline-scripts into delta-range
