1.0.0-alpha.10

• Changed the default theme input path to "theme/input" in preparation for work on dedicated theme folders (see #891).
• Added a new RenderPostProcessTemplates key that prevents running post-processing templates like Razor.
• Added a new ShouldOutput key that controls outputting a particular document to disk (but doesn't remove it from the pipeline like Excluded does).
• Added support for directory metadata (by default as _directory.yaml files).
• Added new ContentFiles and DataFiles settings to control the file globbing patterns.
• Added a new GenerateSitemap setting and Sitemap pipeline to generate sitemap files by default.
• Added a new Excluded key that indicates a document should be filtered out of the content or data pipeline.
• Fixed a bug with feeds not flattening the content document tree.
