Soy is gaining support for parsing/validating html structure and as such a number of patterns will start getting rejected by the parser. This change fixes newly errant soy templates by:
* transforming '<' characters that are not part of html tags to '<'
* inserting whitespace following tag names so that they are unambiguous
* changing templates not rendering html to kind="text" so html rules don't apply
* fixing control flow such that all tags (and quoted attribute values) are completely defined within a single control flow block. In some cases this required extracting {let..} vars or whole templates and in others it required duplicating conditions.
* removing stray unmatched quote characters in html tags.
* fixing incorrectly written html comments
