[1.5.0] Implement TransformToStrict proprietary module

- Factored out strictblockquote from the common definition
- Text module now follows "strict" rules by default
- attr_transform_* now are indexed with string keys, to allow overloading
- Implement ElementDef mergin, and add standalone class variable to ElementDef to prevent half-baked element definitions from masquerading as full ones
- Implement merging global attributes from modules, namely info_attr_transform_post, info_attr_transform_pre and info_tag_transform
- Rename setupInfo() to processModules()
- Fix typo in HTMLModule/Bdo.php
