Conda recipes updates from your friends at Mapbox.

Click is upgraded to 3 (required by Rasterio).

GDAL now includes supporting data and has some OS X specific
build extras (for Mavericks+).

Rasterio has those build extras, too, plus the CLI rio program.
Rasterio 0.16 is going to work very well with Conda.

Hope you like these! I'm going to try to get the GDAL fix upstream
to Conda, too.
Use Conda's sqlite3.
Use git_tag to specify rasterio version
