Conda recipes for Brightway and some of my other code

Uses tips and tricks from Adrian Haas.

Created originally using conda skeleton pypi brightway2, but then modified manually.

Uses script: python setup.py install --single-version-externally-managed --record record.txt to avoid pip re-installing things.

Uses Jinja2 variables the same way that conda-forge does.

Get SHA256 values from the pypi warehouse.
