Add option to report all matched schemes

[hmontenegro]

It would be nice to have an option to report all matched schemes above the score, instead of reporting just the best one.

Case in point: for an isolate genome which is not truly an isolate, the output is:

contigs.fa	abaumannii_2	15	Pas_cpn60(6)	Pas_fusA(6)	Pas_gltA(8)	Pas_pyrG(2)	Pas_recA(3)	Pas_rplB(5)	Pas_rpoB(4)

However, --debug shows:

$VAR1 = [
          'abaumannii_2',
          15,
          '6/6/8/2/3/5/4',
          100
        ];
$VAR2 = [
          'bcereus',
          1280,
          '33/8/13/19/8/17/201',
          100
        ];
$VAR3 = [
          '-',
          '-',
          '-/-/-/-/-/-/-',
          0
        ];

Showing multiple matching schemes would allow quick screening of contaminated isolates. The default for this option would be to report the best match, so no changes to current behaviour.
