Add hugo.BuildCount

[bep]

See https://discourse.gohugo.io/t/how-should-i-store-dynamic-data-in-the-page-object-hugo-serve-w/52514/2

Deprecating Page.Scratch was the right thing to do, but the example above may be a rare useful example of the old behavior.

It would be simple to add a hugo.BuildCount method (I guess starting at 1).

In the topic above, you could possibly do:

{{- if ne (.Page.Store.Get "myCounter")  hugo.BuildCount -}}
<script type="text/javascript" src= '(...)'></script>
<style>(...)<\style>
{{- end -}}
{{- .Page.Store.Set "myCounter" hugo.BuildCount -}}

For the use case described in the forum, isn't it sufficient to check the ordinal?

The ordinal for the first foo shortcode on a page may still be ... 5, so I don't see how.

... if I remember the ordinal logic correctly:

{{< foo >}} // 0
{{< bar >}} // 1
{{< foo >}} // 2

For some reason I thought that number was tracked separately for each shortcode, and our (my) docs on the subject need some adjustment:

I guess we could possibly change that logic, which would make this issue go away....

Edit: I guess it would not make this go away for nested shortcodes.

The forum topic related to this issue was handled with the HasShortcode method. I think my source of confusion about the shortcode Ordinal was that each render hook type keeps track of its own ordinal, and I forgot that shortcodes don't work the same way.

I have an image gallery shortcode where the details data is stored in a .json file (to be lazy-loaded) and the page position of the shortcode is used for the mapping.

Page.Scratch was perfect for a custom counter (I first tried to use .Ordinal first), but for development the logic is now broken. Personally, I would prefer to have the choice between persistent and volatile storage facilities, but being able to reset my counter between builds would be welcomed as well.
