[1.7.0] Finish implementing legacy elements, begin implementing legacy attributes

- Migrated most unit tests over to XHTML 1.0 Strict to preserve transformation behavior
- Created %Core.ColorKeywords to be shared between CSS_Color and HTML_Color
- Added AttrDef_HTML_Color as AttrType Color
- HTMLPurifier_Config::create(HTMLPurifier_Config $config) now clones the object
- Attribute minimization for HTML implemented in Generator
- Move div@align fix from proprietary to regular set
- Color keywords now map to full six digit hexadecimal codes
- Harness will now tack on per-use-case configuration
