May be relevant for #112 as a pre-condition

A simple usage for this is automatic nested pages, for example _pages/about/contact.md would be saved as _site/about/contact.html.

A more advanced usage could be as an alternative to documentation page grouping where each subdirectory becomes a sidebar page group.

Working on this now, realizing an interesting application. If, let's say, a Blade page is stored in _pages/docs, then depending on the compile order, that page could be saved alongside other documentation pages. Maybe this could be used as a more visible documentation full page search page?

So far:

• Documentation pages now have support for nested directories, here the pages will still be compiled into _site/docs, but the subdirectory name is used to automatically add a sidebar category.
• Blog posts work effortlessly, as to Markdown pages 😮
• Blade pages needs to be updated to generate default title from the basename* Edit: fixed

*Would be neat to add a static parser to find @php($title = 'foo') tags to get the Blade page titles.

Could be cool to add a configurable option to automatically put nested Blade/Markdown pages in dropdowns (#76) in the navigation menu.
