Tidy replaced with HTML 5 parsing algorithm

 * See the frequently asked questions for more details

The HTML 4 based Tidy library has been replaced by a pure-PHP HTML 5 parser to clean up improper wikitext in a modern and standards compliant way. If your content relied on some of the tidy fix-ups that are not being continued, they will need to be fixed. [Something about how in the long-run this will all be better. Pointers to Linter and ParserMigration].
