Fixed:
* In Samplevis HTML visualisations, the automatic allele selection was
  only checking the number of reverse reads for the 'minimum number of
  reads per orientation' setting.
* In Samplevis HTML visualisations, automatic allele selection would
  fail to select alleles that had exactly the given minimum number of
  reads.
* FDSTools would sometimes calculate incorrect and even negative repeat
  counts when producing TSSV-style sequences and allele names for
  sequences that did not exactly fit the STR structure given in the
  library.

Improved:
* The Samplestats tool now offers the same possibilities to mark alleles
  as Samplevis HTML visualisations do.
* In Samplevis HTML visualisations, user-removed alleles now have a line
  through their table row.
* Added a reference to https://docs.python.org/howto/regex in the sample
  tag parsing options section of the help text of many tools.
* FDSTools will now do a better job of finding the longest possible
  match of the STR repeat definition to produce TSSV-style sequences and
  allele names for seqences that do not exactly fit the STR structure
  given in the library.

Added:
* New visualisation type 'allele'. With Allelevis, you can generate a
  graph of the alleles of the reference samples (output from
  Allelefinder). (Known bug: it has a 'funny' amount of padding.)
