Issue with post frontmatter and pagination

[thoemmi]

I have some problems when using post's frontmatter and paginating. Additional properties I define in the a post's frontmatter are not available when I use pagination.

E.g. I have this post:

 --- layout: default title: 'Some post' customfield: 'bar' --- ## Hello World! 

And my index.html look like this

 --- layout: default paginate: 1 title: 'A different title' ---{% for post in paginator.posts %}{{post.title }}-{{post.customfield }}{% endfor %} 

Then the first page is rendered with

 Some post- 

but I expect

 Some post-bar 

I'm always confused by Pretzel's code: on the one hand PageContext has several properties, and on the other hand it has a Bag, where some of the properties are duplicated.

This PR contains "only" a unit test to reproduce the issue. I don't know how to fix it at the moment.

Thanks a lot for the reporting 😃
I know that the paginator is kind of "weird" at best, but I hadn't take the time to investigate it.
Seems the time has come!

So finally it is not linked to the paginatordirectly but by the way we populate the liquid's template data in LiquidEngine: the paginator is passed directly without processing the data of each of his posts.

So right now the customfield is accessible through post.bag["customfield"].
An evolution could be to pass the paginator in LiquidEngine.CreatePageData but to call a ToHash method, like the one used on ContextDrop, which will return a Hash of all properties of paginator and call ToHash on each Page.

About PageContext, I think it is because Razor is also supported: it doesn't use page.customfield but @Model.Bag["customfield"] to access to custom values in page. So the properties are needed to facilitate the access to usual values.
