CI/CD: Support for automation (#42)

To hook up to the new CI/CD system, the following changes were made:

- Added/updated conda recipe
- Every commit is now a version thanks to versioneer
- Removed `install_requires` from `setup.py` (dependencies now handled by conda recipe)
- Standardized travis configuration to use latest development builds of QIIME 2

Pair programmed with: @jairideout, @ebolyen, and @thermokarst
