Replaced APACHE_RELEASE_DATE with APACHE_RELEASE number, since branching

a release makes the date meaningless for feature comparisons.  The format is

     jnnffbb    (j = major number, nn = minor, ff = bugfix, bb = beta)

Note that 1.2b11 would have been 1020011 and 1.2.0 would be 1020012,
since the beta sequence numbers are actually X.X.0 releases.
