allow slide design to affect multiple standard pages

modify this minimally and select all standard pages
selected in the slidesorted, unselect them afterwards
and loop over the selected ones.

This looks like it could do with a rework to disentangle
the master/standard pages stuff, but leave it as is in
this commit
