Release 0.6.1

Release 0.6.1 addresses an issue in version 0.6.0 where custom name schemes were not properly picked up, whereas release 0.6.0 introduced modularity to xtypejs, splitting it up into smaller components by extracting various previously bundled functionality into separate optional xtypejs extension modules. The result is a significantly smaller xtypejs library which provides the core type checking and data validation functionality, while still allowing the flexibility to re-introduce the various other additional functionality by applying their corresponding extension modules only when each of their functionality is required. Note that the release split up xtypejs into several modules while still maintaining the existing xtypejs API. Therefore, existing applications may now just require several modules, though most will still require just the main xtypejs module. With the much leaner library, xtypejs is also now listed on microjs.com.
