Title: Add information about pages and items in the current page

The `pagination` object stored in the metadata now contains more
information:
- total number of pages
- index of the first item in the page
- index of the last item in the page
- number or items per page

The `pagination` object have changed and now contains two sub-object:

page: {
current // current page number
total // total number of pages
next // next page number
previous // previous page number
}
items: {
total // total number of items (for all pages)
per_page // number of items per page (or undefined if it cannot be computed)
first // index of the first item in the current page
last // index of the last item in the current page
}

This is needed to ease the use of the `pagination` object in templates, as Handlebars do not allow arithmetic in templates.
