I went ahead and refactored to use a command line flag instead of tying the raw
rank to a specific RankScheme. The command line flag is -a (-r and -R were
taken. Mnenomic: -a for "a"bsolute rank score.)

r2291 in svn trunk implements this change. http://dev.swish-e.org/changeset/2291

It's available in the C lib and SWISH::API Perl lib as ReturnRawRank().

 $swish->ReturnRawRank(1);  # turn it on
 $swish->ReturnRawRank(0);  # turn it off (default)

Unless I hear that this new feature breaks something, it'll be in 2.4.7 when I
(finally) release it this coming weekend.

So *please test svn trunk*.
