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.

Previously, if an absolute munge URL location was used, HTML passed through
HTML Purifier multiple times would be munged multiple times. This patch
checks if the output URI has the same URI as the input URI; if they do,
the munge is considered unnecessary and discarded.

As part of its duties, URIDefinition determine the base URL and the host URL
of the page based on the two corresponding configuration directives. The
DisableExternal URIFilter, however, bypassed this check by directly checking
%URI.Host. This fix forwards the call through URIDefinition.

The following changes were made:
* Create --type parameter which accepts 'htmlpurifier', 'phpt', 'vtest', etc.
in order to execute only that class of tests. This supercedes --only-phpt.
* Create --quick parameter for multitest.php, run only the tips of each
release series.
* Create --distro parameter for multitest.php, supercedes --exclude-normal
and --exclude-standalone.
Also, a grep for htmlt tests was added, although add_tests() doesn't do
anything with it yet.

By default, the DirectLex and DOMLex behavior with stray angled brackets
varied a great deal due to their implementations. A little known directive
%Core.AggressivelyFixLt attempted to match DOMLex's behavior with DirectLex's,
but it was off by default. By turning it on by default, users now enjoy these
benefits, and performance-minded users can turn it back off.
Also, several refinements to stray angled bracket parsing was made. Specifically:
* DirectLex: Handle each left angled bracket individually, which prevents
strange behavior as reported by eon.
* DOMLex: Iterate aggressive lt fix, so that stacked brackets like << are
handled.

Previously, attempting to set %Core.Encoding to an encoding iconv didn't
know about would result in a silent failure, with the return of the
boolean false. Now it will fatally error out.

The MakeWellFormed strategy uses metadata from HTMLDefinition in order to
determine whether or not tokens need to be converted or tags need to be
auto-closed. While this functionality is good to have, it is by no means
essential, and MakeWellFormed should not error when this information is not
available.

Injector rewind: Injectors can now use the method rewind() in order to move
the input index backwards, so that they can reprocess tokens (other injectors
are not affected by a rewind). This functionality was necessary to implement
nested node removals in %AutoFormat.RemoveEmpty.
End to start ref: To facilitate rewinding, HTMLPurifier_Token_End now
maintains a reference called $start to the starting token for their node.
%AutoFormat.RemoveEmpty removes empty nodes. Lots of people have requested
it, so here is a partially effective implementation. Because it is implemented
as an Injector, it's not possible for it to handle newly introduced empty
nodes by later validators, specifically auto-closing and child validation.
The Injector is only meant to be used on HTML-ish languages.

Prior to this commit, the name attribute was unilaterally removed, except
for Strict doctypes or a heavy TidyLevel, when it was converted to an id
attribute. As name is actually permitted in both HTML 4.01 Strict and
XHTML 1.0 Strict, although deprecated, the more sensible default behavior
is to allow it unless TidyLevel is heavy.
Our implementation is slightly stricter than the specs, as name attributes are
treated as first class IDs, disallowing <a name="foo" id="foo"> or duplicate
names. The former should be treated as a special case, but that will be
a separate commit.

Previously, MakeWellFormed processed tokens and appended them onto an output
array, which was presumably immutable and inaccessible to Injectors. By
having MakeWellFormed operate directly on the input array, the strategy
saves memory and will also allow for a rewind implementation, as a unifying
the two arrays allows Injectors to easily determine an index behind them they'd
like to reset state to.

Some implementation notes: not all comments are valid; HTML makes sure
double-hyphens and trailing hyphens are not found in comments. In addition,
