Initial take on pre-loading all slides
Control visible slid

Switch to adding and removing "active" class to control visible slide
instead of using :target pseudo-class (which doesn't appear to work
with dynamically loaded elements).

Switch to using a class instead of id for page number element.

Cleanup transition from full to list mode

Update CSS for active slide in list mode
Move script to engine/ directory

Workaround jQuery not handling ':' in selectors

Revert to plain JavaScript DOM for selecting elements by id as jQuery
fails if there is a ':' in the identifier used as a selector;
apparently they interpret it as a pseudoclass. Oh.
Fix cover and graphic CSS
Push z of cover images down
Move stylesheet to full and list
Consolidate to single CSS file
