patches for copying atimes

Hi.
Here's a patch for copying the atimes of files when -t/--times is
given. I bumped the protocol to 29 since it sends more data over the
wire. It obviously does not send the atime if it's sending data to an
older rsync version.
It passes all the tests (including the added atime.test) for me on a:
Linux Debian/3.0 gcc 2.95.4 (debian), glibc 2.2.5 system.
Any questions/feedback? I certainly think that this functionality
would be useful for others. Note that this is orthogonal to updating
(or not) the atimes on the source tree.
