[mew-int 2430] Mew version 5.2.53

[Kazu Yamamoto ( 山本和彦 )]

Hello all,

I have released Mew 5.2.53:
	http://www.mew.org/Beta/mew-5.2.53.tar.gz

The highlight of this version is a feature called "dialog". Type 'V'
on the current message and you can obtain a list of messages which
have relationship with it on Virtual mode. Please read section
"Virtual mode" of info for more information.

I have removed many obsoleted code to clean up Mew. Please use Emacs
21.4 or Emacs 22.1.
