POE: CHANGES - Changes In POE 0.20

	* POE.pm, README: Final preparations for releasing POE 0.20.

	* CHANGES: Version 0.20 and beyond use auto-generated CHANGES files
	based on POE's cvs log.

	* lib/: Makefile-5004.pm, Makefile-5005.pm: Have Makefile.PL touch
	the CHANGES file so that "make dist" will find it.  Even though we
	generate CHANGES from the CVS log, WriteMakeFile needs to see
	something there first.

	* lib/Makefile-5004.pm: Perl 5.004_03 didn't like AUTHOR and
	ABSTRACT, so I removed them.

	* lib/Makefile-5005.pm: Perl 5.005_03 didn't like bareword IO::Poll
	on the left side of the => operator.  I put quotes around it, and
	things seem to be generally better.

	* POE/Kernel/Tk.pm, t/06_tk.t: Philip Gwyn discovered a
	"modification of a read-only value" error in POE::Kernel::Tk's file
	watcher pause/resume code.  I adapted a previous plain-Tk testcase
	to verify the behavior outside POE.  It's there in Tk on Perl
	5.004_05.  The testcase doesn't fail with Perl 5.005_03, so it
	looks like an incompatibility between Tk and the older version of
	Perl.  I've decided to discontinue Tk support in Perl versions
	before 5.005_03.  If anyone has a vested interest in the older
	Perls + Tk + POE, I can provide the test case for their debugging
	pleasure.

	* t/27_poll.t: Philip Gwyn spotted that TestSetup wasn't being used
	here.  That's what I get for testing stuff on systems that have
	everything.

	* lib/: Makefile-5005.pm, Makefile-5004.pm: Added the second bit of
	sungo's Makefile magic.  This part generates POE's CHANGES
	automatically from the cvs log.  No more twiddling with it by hand!
	 Yay!  P.S., Everybody better commit decent change descriptions, or
	else.

	* lib/Makefile-5005.pm: Remove IPC::Run (we're not using it yet).
