Genhub

Fixed
- Removed gene model with overlapping exons causing processing issues in *C. reinhardtii*.

Fixed
- Removed unnecessary `Fragment` column from `.iloci.tsv` table. Redundant with `LocusClass=fiLocus`.
- Removed outdated code for computing `LocusClass`.
- Fixed feature for specifying iLocus label format.

Added
- Integration with codecov.io.
- Lots of genome recipes
- *Anopheles gambiae*
- *Homo sapiens*
- *Theobroma cacao*
- some version-specific recipes
- TAIR6
- *Apis mellifera* assembly 2.0 / OGS 1.0
- *Apis mellifera* assembly 4.5 / OGS 3.2
- 9 species of green algae
- Implemented the `cleanup` and `cluster` tasks for the main build script.

Changed
- Unit test fixtures to account for AEGeAn's improved reporting of iLocus types.
- Protein checksum for *Xenopus tropicals*, which was recently updated to drop the *Silurana* designation.

Fixed
- versioneer issue with MANIFEST

Added
- Recipe for the rice genome (*Oryza sativa* L. ssp. *japonica*).
- Recipe for a model legume genome (*Medicago truncatula*).
- Batch for all Hymenoptera.
- Multiprocessing support for build script.

Changed
- Complete overhaul of the genome configuration handling (now in the `registry` module).
- Minor changes to the Travis CI configuration.
- Excluded *Danio rerio* config from CI tests, as its resource requirements are right at the limit of what the Travis VMs can handle.
- Updated *Xenopus tropicalis* config to drop the parentheses in the species name.
- Updated *Drosophila melanogaster* config to the latest RefSeq assembly/annotation.
- Moved sha1 and file resolution code from `__init__.py` to `GenomeDB` class.

Added
- Package metadata.

Fixed
- Minor improvements to documentation.
