[1.7.0] Refactor HTMLModule unit tests

- AttrCollections does not barf when an inclusion is not present
- HTMLDefinition configuration directives now use new syntax
- Added %HTML.AllowedModules and %HTML.CoreModules for testing
- Extend Harness so that it can accept a default configuration object member variable
- Refactor modules to use Scaffolding, which defines some custom attributes that allows for the easy testing of attribute collections
