IntegrateMDHistoWorkspace should have keep binning + axis limits option

[OwenArnold]

This ticket is blocks : TRAC11626

Currently you can set P{n}Bins to be [] or [min,max] where [] means exactly keep the binning and [min,max] means integrate between limits.

Russell Ewings has asked for this to occur as a mode in the LineViewer (11626), but the problem comes when you specify the start and stop within the range of the original data. In this case, you want to keep the existing binning, but you also want to exclude any data between the limits. If you do not do this, it will not be possible to reproduce the slice as drawn in the plots.

I suggest that having a [start, 0, stop] syntax should also be allowed. Only zero's would be accepted and would indicate that the current binning should apply.
