correct Pod-Html tests for new Pod-Simple output

Okay, look, I know we should really fix the tests to be more
generic, but that's just not going to happen right now.  Hopefully,
we can ditch Pod-Html before this comes up again.  Maintaining it
as is is sort of a drag.
Bump Pod::Html to 1.19
Update Pod-Simple to CPAN version 3.26

  [DELTA]

  2013-02-27   David E. Wheeler <david@justatheory.org>
    * Release 3.26

    Fixed another test script to skip all tests when Encode is not
    installed.

    Added 'encoding()' and 'detected_encoding()' to return the current
    encoding and the encoding actually to decode the input file. The
    value from "=encoding" is also now kept in the output tree. Patch
    from Patrice Dumas (RT #74390).

  2013-02-16   David E. Wheeler <david@justatheory.org>
    * Release 3.25

    Improved the warning when "=item" types mismatch within one
    "=over"/"=back" block.

  2013-02-14   David E. Wheeler <david@justatheory.org>
    * Release 3.24

    Fixed corner case bug for unlikely scenario in which non-UTF-8
    text could be parsed as UTF-8. Grant McLean.

    XHTML IDs can no longer end with punctuation. Thanks to Smylers
    for the patch.

    Fixed test failure on Perl 5.6.2.

    Changed the default installation location from "perl" to "site" on
    5.12 and higher, since as of that version of Perl, dual-life
    modules no longer need to be installed in "perl" to replace
    in-core versions. Patch from tzccinct.

    Fixed hash order dependency test failures on Perl 5.17. Thanks to
    Yves Orton for the patch.

    Inlined the code that tries to guess a Pod file's encoding. This
    reduces the time Pod::Simple takes to build the core Perl
    documentation by 15-20%. Thanks to Dagfinn Ilmari Mannsåker for
    the patch!

    Added a warning when "=item" types mismatch within one
    "=over"/"=back" block. Marc Green/Google Summer of Code, with
    assist from RJBS.

    Fixed regression introduced in 3.22 in which "C< >" tags were
    incorrectly treated as verbatim text in table of contents items
    emitted by Pod::Simple::XHTML. Thanks to Randy Stauner for the
    report and to Thomas Sibley for the fix!

    Loosened up the matching of "L< >" tags for man pages so that they
    allow names with dots, underscores, and any other chararacters
    other than "/", just so long as they end in '[(][-a-zA-Z0-9]+[)]'.
    Thanks to Dave Rolsky and Kevin Ryde for the reports (RT #82975 &
    RT #82972).

    Fixed inverted mapping of "keyboard" to "kbd" in
    Pod::Simple::HTML. Thanks to Robert Boisvert for the bug report
    (RT #79201).

    Added two new Tagmap entries to Pod::Simple::HTML: "preformat"
    maps to "pre", and "teletype" maps to "tt". Suggested by Robert
    Boisvert (RT #79201).

    "X< >" tags are now ignored by the pull parser when it searches
    for titles, as is any trailing whitespace. Thanks to Patrice Dumas
    for the report (RT #74389).
