This release introduces four new utility methods for working with SpatiaLite. Thanks, Chris Amico. (#330)

• sqlite_utils.utils.find_spatialite() finds the location of the SpatiaLite module on disk.
• db.init_spatialite() initializes SpatiaLite for the given database.
• table.add_geometry_column(...) adds a geometry column to an existing table.
• table.create_spatial_index(...) creates a spatial index for a column.
• sqlite-utils batch now accepts a --batch-size option. (#392)
