LibLine: Properly paginate suggestions in XtermSuggestionDisplay

Browse source 
This commit adds back suggestion pagination, and makes it 10x better.
Also adds a "< page m of n >" indicator at the bottom if there are more
suggestions than would fit in a page.
It properly handles cycling forwards and backwards :^)
