genbank.pm: Another tweak to "_read_GenBank_Species" regex
to fix wrong parsing of NC_021902 long ORGANISM line:
  ORGANISM  Salmonella enterica subsp. enterica serovar Newport str.
            USMARC-S3124.1
            Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales;
            Enterobacteriaceae; Salmonella.

HMMERHSP: For HMMer report parsing, changed "$hsp->bits" to
be consistent with "$hit->bits" behaviour, so now it returns
zero instead of undef (since HMMer don't use 'bits')
hmmer.t: Added tests to document "$hit->bits"
and "$hsp->bits" returning value 0
t/Tree/TreeIO/nexml.t: A close function was being used on
a scalar instead of a filehandle, changed it so the object
close the temporary file filehandle. Also cleaned format.
