Changes from 0.10:
0.12 Mon Aug 20 16:06:50 PDT 2007
    - Make this a release

0.11_03  Wed Jun 20 12:12:36 PDT 2007
    - Fixed a bug in backward-compatiblity code to handle multiple
      hooks in one add_trigger() call. (Thanks to mark addison)

0.11_02  Sun Jun 10 18:09:58 PDT 2007
    - Added a test to make sure $_ is not clobbered
      (Thanks to mark addison)
    - Killed the hidden feature to add multiple hooks in one
      add_trigger() call because it interfers with named parameter style
      calls. (Thanks to clkao)

0.11_01  Mon May 28 21:03:03 PDT 2007

    - Added support for abortable triggers.
    - Added named-parameters calling convention for add_trigger
    - Added new last_trigger_results method and began capturing trigger return \ 
values.

    - FUNCTIONALITY CHANGE: When no triggers are called for a trigger point, the \ 
return value is now '0', not undef.
      (Thanks to Jesse Vincent)

0.11  Thu Feb 22 19:02:09 PST 2007
        - Fixed a bug due to Class::Data::Inheritable, where
          triggers added to the superclass after trigger is added in
          the child class are ignored in the child class.
          See t/03_inherit.t for example.
