Log Message:
Update to version 0.23.

Changes since last packaged version (0.11):

[Changes for 0.23 2008-05-09]
* RT now respects the --datafile flag to rt-setup-database when
  used with --action acl or --action schema.
  Don't pass the initialdata file when we're doing schema changes

[Changes for 0.22 2008-03-25]
* Add local lib path to the @INC when we call any script that may
  load RT config.

[Changes for 0.21 2007-12-07]
* LICENSING CHANGE: This compilation and all individual files in it
  are now under the permissive "MIT" license.  See the COPYRIGHT
  section in README for the new terms.
* Cleanup on POD, changelog, README, etc.
* Bump dependency of Module::Install::Admin to 0.40, so we can make use of
  all_from() and drop the parentheses in Makefile.PL commands.

[ Changes for 0.20 2007-12-05]
* Support for new RT 3.7 "RT Plugin" mechanism.
* No longer tries to write to the global local perl man and site directories
  (packlists and manpages), instead installing them within the RT hierarchy.
