Version 0.5

This update brings a new output format to stringMLST.
NOtably, versions prior would return no output (columns omitted)
for alleles which had 0 kmer hits.  stringMLST will now return
"NA" values for alleles with no hits.  This should hopefully
make the output more obvious in cases such as #35
