Description:
Allow some intermediate slides to be skipped in the counting and one terminal slide to be used as the total count.

Actual Results:
All slides (except hidden ones) are counted in <number> and <count> counters.

Expected Results:
The slide counters (<number> and <count>)could be improved:
1) by optionally allowing to skip one slide in the counting, as if it was hidden (typical example: a subtitle aka “centered text” slide.)
2) by tagging one slide to be the last one, typically the conclusion slide.
The following ones are usually back-up ones, and should not be counted.
The <number> of the first slide tagged as "terminal" is used as <count>.
