0.2 - sitemap.xml

Caxton now uses a middleware pipeline passing a list of files that have been copied/built into the output directory.

How configuration is accessed was rewritten to allow more flexibility and extendability for the future.

• Changed the files block/allow configuration to exclude/include
• caxton.*.json can be used to implement environment overrides
• A sitemap.xml is built and included in the output directory ready for publishing
