Update to 1.13:

1.13 Wed Sep 28 2005
	- Fixed a minor POD bug in the synopsis

1.12 Fri Sep  9 2005
	- Added a fix for classes with insanely broken ->isa methods
	  that cause Perl to die.

1.11 Tue Sep  6 2005
	- It occured to me after I added ->find that what it _really_ is
	  is a way to find all the subclasses, but then include the class
	  itself in the returned list. This method makes much more sense
	  it I don't return the class itself, and rename it ->subclasses
	- Fixed broken Makefile.PL

1.10 Mon Sep  5 2005
	- Added the ->find method
	- Cleaned up and reorganised the POD
	- Made sure all return conditions are documented properly
	- Converted to Module::Install
