[IRCServices] Services 4.5.3 released

[Andrew Church]

     Services 4.5.3 has been released, and can be downloaded from:

ftp://ftp.esper.net/ircservices/ircservices-4.5.3.tar.gz
ftp://ftp.esper.net/ircservices/ircservices-4.5.3.diff.gz

ftp.ircservices.za.net and the mirrors should have it shortly.

     This release has a number of features I had hoped to include in
4.5.0 but didn't because I was going through too many pre-releases.
Notably, channel modes can now be buffered (see MergeChannelModes in
data/example.conf), there is now an HOP command to parallel the
SOP/AOP/VOP commands for Unreal servers (and yes, I know "hop" is a
word, but so is "sop", so live with it), ChanServ has an ENFORCE
option to enforce +o/+v(/+h) modes like some of the pre-releases did,
and the ChanServ CLEAR command can now clear exceptions and halfops
as well on servers that support them.  The changes aren't major
ones, so I hope no major bugs will come out, but keep in mind that
this release may not be quite as stable as previous ones, especially
if you use the new features.

     This release also fixes a couple of potentially nasty security
bugs, one with the SU command (oops) and one letting people use the
VOP command to delete people with higher access levels (oops again).
I hate to spring fixes like these on everyone in a possibly-not-
quite-stable release, but c'est la vie.  If anyone notices any
problems, let me know and I'll release a fix promptly.
