%URI.Munge incorrectly munged URIs that pointed to the
same host as the current website (it did, however, have
the correct behavior for when the munge URL was on the
same server).

When precision dictates that a number be zero padded, we cannot give sprintf()
a negative precision specifier. This commit implements manual negative precision
printing of floats, taking into account common rounding errors with floating
point numbers.

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).

* Added Charsets and Character attribute types
* Fix a heavily recursive form of ContentSets, this allows a content-set
to include another content-set which includes another content-set, and
so forth.

This is a very large commit that includes numerous improvements to the
AutoParagraph injector. These are:
* Rewritten flow control of the injector to use almost exclusively
binary conditionals.
* Improved inline documentation with "State" comments, which give concise
examples of what the token stack looks like at flow points.
* Documentation for all flow branches, even those with no actions.
* Factoring out of common operations to improve readability, especially the
new iterator private methods.
* Expanded test-suite which covers new flow points, and corrects some errors
in previous cases.

The newest autoclose code uses the elements property in whether or not an
element should be closed by a particular tag. The heuristic is simple; if
the element doesn't allow that tag as a child, it closes the parent
container. This doesn't work, however, with <blockquote>, which while not
allowing inline styles under Strict doctypes, requires them to be passed
through MakeWellFormed.
The fix was to transition MakeWellFormed to call a method to retrieve the
elements, and then have StrictBlockquote implement a special version of
this method. Future versions of HTML Purifier may be more flexible in this
regard--further study of the HTML5 specification is required.
