Set page size and orientation for the whole presentation

Set Page Size and Orientation under Presentation Settings so they apply to the whole presentation rather than to a single sheet.

1. Page Size (A4/A3/A2/A1/A0) and Orientation (Landscape/Portrait) sit under Presentation Settings, not per sheet.
