Added

• Add replace_view migration statement, which issues CREATE OR REPLACE VIEW rather than CREATE VIEW or DROP VIEW and CREATE VIEW.
• Schema-qualify views outside the 'public' namespace, such as scenic.searches

Fixed

• Singularize generated model name when injecting into class. Previously, pluralized names would issue a warning and Scenic would attempt to insert model code into the pluralized model file.
• Convert shell-based smoke tests to RSpec syntax.
