An uneeded cast from size_t to unsigned long was causing the windows
build to fail.

On the instrument viewer's draw interface, it adds a button in charge
of masking complete tubes or banks.

After the user has picked a single pixel, contrary to other masking
options, editing the shape is not possible and thus the default
behavior should be to stay on this option.

Adds the option to mask a single pixel of a detector, similarly to the pick
option.

This commit adresses the integration scroll bar on the instrument render
tab. A previous commit deleted this bar altogether when it was not
needed, mainly for monochromatic workspaces. But a few methods,
especially in MantidPlot, actually depends upon the attribute being
initialized.

As such, the integration scroll bar object is again initialized in every
case, but a flag "hidden" have been added, which allows it to be created
as a mere shell, without any component that would show onscreen.

On the instrument widget pick tab, the plot which shows the spectra
for all wavelength bins for the detector is useless when the workspace
is monochromatic. As such, it is collapsed if the workspace is
monochromatic.

In the case of monochromatic workspaces, there is only one bin.
Thus using the integration scroll bar in the instrument render tab
 is nonsensical, and it can be safely removed.

This adds a button to reset the view to its default parameters
in the intrument render tab.
