Make 'svn propset svn:executable' take effect immediately.

This is in contrast to our other "magic" props; svn:eol-style and
svn:keywords don't tweak your working file until you commit.  But Karl
rightly points out that this isn't really a problem; users aren't
going to expect all these magic props to behave exactly the same.
Tweaking file contents is much more invasive than tweaking permissions.

* props.c (svn_wc_prop_set): if the svn:executable property is either
  set or deleted, then do a chmod +x or -x on the working file.
