Sub-Pages

[sbrl]

We should implement sub pages.

Things that need checking / doing:

• Check that the page name escaper correctly handles forward slashes
• Add support for sub-pages to the page index
  • Add field that indicates whether a given pages has any sub pages
• Update the page-list extension to support sub-pages
• Add support for sub pages to the page index rebuilder
• Allow sub pages to be saved in sub folders
• Display a configurable list of sub pages on pages that have sub pages

Update:

Bugs to fix before this is done:

• Fix issue Non-existent subpage parents aren't added to $pageindex->$page->subpages #11 - Non-existent subpage parents aren't added to $pageindex->$page->subpages
• Fix issue Creating a page with a non-existent parent doesn't cause the parent to be created #12 - Creating a page with a non-existent parent doesn't cause the parent to be created
• Fix issue Creating a sub page doesn't result the subpage[] entry being updated #13 - Creating a sub page doesn't result the subpage[] entry being updated

Updating the page name escaper to allow forward slashes is easy - it's adding the field that gives a list of all the sub pages every page has that will be slightly more challenging. Perhaps for the page index rebuilder we could add this field in after the index has been built.

The page index rebuilder works with subpages now!
You can also create / save subpages too, but the page index doesn't get updated quite right yet (issue #13).
