Feature request: please add support for slide numbers

[refaelsh]

Hi all,

According to the AsciiDoctor RevealJS docs I can use this:

:revealjs_slideNumber: true

But, in RefaelJS docs, there are more options.
For example, I would like to do this:

:revealjs_slideNumber: c/t

Please add support for the above.

Thanks. Refael.

Reveal.js 3.7.0 introduced many new configuration options which we don't support already. We have an issue open about it: #208.

I'm going to keep this one open because I might forget that slideNumber is no longer only a true / false toggle.

Started working on this one. Tested many cases.

Quoting the parameter works to a certain extent because every new reveal.js feature starts working except that there is no way to disable slides numbers even with no attribute value or without even the :revealjs_slidenumber: being set.

This case will need a specific ruby helper where we will return quoted or unquoted values based on what the input is.

Ok, I finally succeeded with the helper. I made a rookie mistake while debugging it. All I need is add more test cases and I'll have a PR soon.

Fixed with the merge of #239 into master. Will be part of the upcoming 2.0 release.
