Log Message:
Update to version 1.61.

While here fix HOMEPAGE.

Changes since last packaged version (1.57):
1.61
- fixed error reporting: die on fatal errors, warn otherwise
  (in particular, warn rather than die on <xsl:message \ 
terminate="no">)

1.60
- fix a huge memory leak in transform_file (bug #1314)
- make it clear from the docs that output_string returns bytes (bug #8875)
- added missing type-casting to fix compile-time warnings (bug #18508)
- using call_* instead of perl_call_* (perl_ variants are obsolete)
- in callbacks, POPs on error before croaking, otherwise it has no
  effect (and we probably leak)
- added test case which used to fail (provided in rt #15723)
- apply patch for Makefile.PL for non-standard libxslt paths (bug #16224)
- fix segfault with registered functions returning nodes
- fix leaks in parse_stylesheet
- error reporting

1.59
- (revision bumped to match XML::LibXML)
- adapted for new XML::LibXML::InputCallback API
- support for static linking against libxml2
