Many changes:

Made the VCALC panel aware of all of the binning options
Corrected the behavior of the VCALC preset conditions
Adjusted how the Slit data is binned so that there are not duplicated q-values in the output

Made Absolute scaling aware of the back detector. Now the ABS String in the protocol has a second
set of scaling constants tagged with "_B" for the back detector. There is an added button
on the protocol panel to set the second set of constants. For the back detector, the read noise
is subtracted by reading it from the empty beam file (shifting over to the right by one box width)
All of the associated abs procedures are now aware of this.
More error checking needs to be added.

Back detector image is now shifted upon loading of the data. the default mask takes this into account
and masks out the padded (zero) regions.

in the protocol, DIV and MSK do not use grep any longer. it was just way too slow. Now it depends on

the file name having DIV or MASK respectively.

Raw data files can now be added together, in the usual way from the protocol panel.
