sd: Use unique Page ids for better multi-view support + unit test

... instead of using simple IDs which are assumed to be one greater than
the slide position everywhere in the codebase.

Use a 16 bit static counter and uniquely assign page ids to SdPage
objects. This helps in identifying which slide was already selected
in second view before any slide is deleted in the first view. Otherwise,
using simple positions to keep track of it leads the second view to end
up selecting the wrong slide after any slide is added or removed in the
first view.
