Rework page counters for skipping and resets.

Browse Source 
Solves #513

This adds the .skipCounting and .resetCounting classes for causing
a page number to not be incremented or to reset the number at 1.

The ToC Snippet is corrected to match the displayed page numbers
while correctly tracking the page ids.
