Genhub

Changed
- The `genhub-build.py` script is now `fidibus`, and the CLI was updated.
- Pdom, Pcan, and Dqua now default to RefSeq genomes, with Toth Lab and CRG genomes available under labels Pdtl, Pccr, and Dqcr.

Fixed
- The `cluster` build task now uses `-M 0` by default.
- The `Registry` class was simplified.

Added
- The build script (now `fidibus`) now has support for custom genomes.
- Sequence IDs are now reported for iLocus and miLocus tables.
- New script for creating a piLocus summary table.
- Recipes for chick pea, cabbage, and soybean.
- Recipes for another mosquito (*Aedes aegypti*) and a spider mite (non-insect arthropod).
- A `--shuffled` option to several scripts for reading from `*iloci.shuffled.tsv`, and improved access from the GenomeDB class.

Fixed
- Correctly included missing script in `setup.py`.

Added
- New recipe for cotton.
- New recipe for *Daphnia pulex*.
- New script for creating an iLocus summary table.

Fixed
- Updated test data files to compensate for corrections to LocusPocus' reporting of iLocus type.

Added
- Added `seqfilter` to RefSeq module and .yaml configs.

Fixed
- Used new `seqfilter` mechanism to eliminate redundant patch and variant data from human and mouse genomes.
- Updated rice recipe following an update to the corresponding RefSeq entry.

Fixed
- Filled out partial implementation of `--delta` option for the build script.
