Previous design of injector streaming involved editability only to start, empty and text tokens, because they could be safely modified without causing formedness errors. By modifying notifyEnd to operate before MakeWellFormed's safeguards kick into effect, it can be converted into a handle function, allowing for arbitrary modification of end tags. This change involved quite a bit of restructuring of the MakeWellFormed code, including the moving of end of document tags to inside the loop, so rewinding on those tags would be functional, increased reuse of the end tag codepath by code that inserts end tags (as they could be changed out from under you), and processToken modified to have an extra parameter to force re-processing of a token if the original token was an end token. We're not exactly sure if handleEnd works at this point, but the important talking point about this refactoring is that nothing else broke. Also, a number of convenience functions were moved from AutoParagraph to the Injector supertype (specifically: forward, forwardToEndToken, backward, and current). Signed-off-by: Edward Z.

All about HTML Purifier
HTML Purifier is an HTML filtering solution that uses a unique combination
of robust whitelists and agressive parsing to ensure that not only are
XSS attacks thwarted, but the resulting HTML is standards compliant.
HTML Purifier is oriented towards richly formatted documents from
untrusted sources that require CSS and a full tag-set. This library can
be configured to accept a more restrictive set of tags, but it won't be
as efficient as more bare-bones parsers. It will, however, do the job
right, which may be more important.
