Made sequence translation code work under Python 2 (hopefully).
3.1.31
Not secure
Added `sam-coverage-depth.py`.
3.1.30
Added `--minGenomeLength` to `make-protein-database.py`.
3.1.28
Not secure
Removed the unused `taxonomy` (`VARCHAR`) column from the genomes table of the protein database.
3.1.27
Not secure
Fixed silly bug in alignment filtering code that was somehow not tested.
3.1.26
Not secure
Added `--percentagePositiveCutoff` argument to `alignment-panel-civ.py` and `noninteractive-alignment-panel.py` and all that implies, down to reading DIAMOND output with the `ppos` value, storing it, restoring it, and filtering on it in `dark.alignments.ReadsAlignmentsFilter`, plus tests.
