Update to 1.123
Update DEPENDS

Upstream changes:
1.123 2014-11-11

    [Dependencies]
    * Now requires PPI-1.220 which has numerous bug fixes. This may
      eliminate the need for some "## no critic" markers you inserted to
      work around those bugs. The "ProhibitUselessNoCritic" policy should
      help you find them.

    [Miscellanea]
    * Fixed a typo in the Variables::ProhibitPerl4PackageNames message.

1.122 2014-08-25

    [Dependencies]
    * Now requires PPI-1.218 which has numerous enahncements and bug fixes.
      Also now requires Readonly-2.00, which obviates the need for Readonly::XS
      to get fast constants.

    * File::HomeDir, File::Which, and Term::ANSIColor are all required now
      instead of being optional or recommended. This simplifies our test code
      and ensures consistent optimal behavior for all users.

    [New Policies]
    * Added two new policies: BuiltinFunctions::ProhibitUselessTopic and
      RegularExpressions::ProhibitUselessTopic.

    [Miscellanea]
    * Updated the perlcritic.el script to use modern Emacs hooks.
      Thanks to @intrigeri and the Debian team for the patch.  Fixes GH #556.

    * Removed all the internal RCS keyword boilerplate blocks that were never
      getting expanded.
