0b9db1f54b Allow non-static autoload methods w/ PHP >= 5.2.11 
HTML Purifier loads itself as the first autoload function by
unregistering all existing functions and re-registering them after
registering itself.

Originally an exception was thrown when a non-static object method was
encountered as the behaviour of spl_autoload_functions() did not return
the object instance, but only the class name.  This was filed on PHP
bugs (#44144).

The bug was fixed for PHP >= 5.2.11 and >= 5.3

d3abcb90e3 Rewrite CSS url() and font-family output logic. 
The new logic is as follows:

* Given a URL to insert into url(), check that it is properly URL
  encoded (in particular, a doublequote and backslash never occurs
  within it) and then place it as url("http://example.com").

* Given a font name, if it is strictly alphanumeric, it is safe to omit
  quotes. Otherwise, wrap in double quotes and replace '"' with '\22 '
  (note trailing space) and '\' with '\5C ' (ditto).

We introduce expandCSSEscape() which is a hack for common parsing
idioms in CSS; this means that CSS escapes are now recognized inside
URLs as well as unquoted font names.

faf28682ad Manually work around PEARSax3 E_STRICT errors. 
Previously, my development environment was not running the PEARSax3
tests because my environment was set to E_STRICT error handling, and
thus the tests were skipped.  Relax this requirement by making the
wrapper class E_STRICT safe.  This introduces a few failing tests.

Also update TODO and add another fresh test.

ba9fd175d7 Make extractBody not terminate prematurely on first </body>. 
Previously, if two </body> tags were present, HTML Purifier
would truncate everything after the first </body>.  This is
not ideal behavior; so HTML Purifier has been changed to
match up to the last </body>.

This fix is slightly hackish, as we simply treat comments as whitespace.
This should largely be correct, and breaks no current test cases,
