Planner: add migration script to drop planner tables from autotest_web database
This migration script properly drops planner tables when going to this (066)
schema version, and creates all tables when going back to version 065. This
last bit is huge, incorporating bits from schema_051.sql and other migration
scripts. I wonder if it's time to rebase the schema version.
